SET_COMP Block Monitors the DRAIN terminal voltage, and outputs a signal to turn ON the FET if the DRAIN terminal voltage is less than or equal to -100mV (Typ). 2. RESET_COMP Block Monitors the DRAIN terminal voltage and outputs a signal to turn OFF the FET if the DRAIN terminal voltage is more than or equal to -6mV (Typ). 3. Compulsion ON TIME Block When the FET is turned ON due to SET_COMP detection, noise occurs on the DRAIN terminal. To prevent the noise from turning OFF the FET, an ON state should be forced for a certain time. Compulsion ON time is within a range of 0s (None) to 3.5s, which is different for each series number (refer to page.1 table). 4. Compulsion OFF TIME Block When the FET is turned OFF due to RESET_COMP detection, resonance waveforms appear on the DRAIN terminal. To prevent the noise from turning ON the FET, an OFF state should be forced for a certain time. Compulsion OFF time is within a range of 1.3s to 4.6s, which is different for each series number (refer to page.1 table). Operation sequence of each block is shown on the figure below.

Operation sequence About Maximum Input Frequency The Maximum Operating Frequency of the IC depends on the Compulsion ON/OFF Time. For example, BM1R00026F and BM1R00146F Compulsion ON and OFF Time is both equal to 0s. Considering a variation of 9%, the maximum input frequency is given by the following: fMAX = 1 / ((0s + 1.3s) x 1.09) = 706kHz However, since the frequency varies greatly due to the input voltage and load, it will be necessary to select the series in accordance with each application. www.rohm.com (c) 2016 ROHM Co., Ltd.

DRAIN terminal voltage starts counting when the rising edge of the output voltage exceeds VCC x 1.4V (Typ). In addition, the recounting starts when it detects another rising edge. The synchronous rectification FET will be forced OFF after the set time has elapsed. The time can be adjusted by varying the resistance value of the resistor connected to the MAX_TON terminal. The relationship between the resistance value (RMAX_TON) and set time (TMAX_TON) is described as follows: RMAX _ TON k t MAX _ TON s 10k / s Calculation Example: If you want to set the maximum ON time to 10s, the value of RMAX_TON is as follows: 10s 10k / s 100k However, the formula above is for an ideal approximation only; it is still strongly advised that the operation of the actual application should still be verified. By setting this time, it becomes possible to prevent the simultaneous ON operation of the primary side and the secondary side in continuous mode. The drive sequence in continuous mode operation is shown in the figure below: VOUT I2 I1 Primary Side Controller (3) (1) Np Ns VH Vf + - (1) VG1 GND LFB VG1 VG2 RDRAIN2 I1 RDRAIN1 D1 GATE DRAIN VCC VDS2 I2 LDO BLOCK VCC x 1.4 DRAIN_COMP - R1 Driver + VCCx1.4 SET_COMP S + C1 VDS2 -100mV 0V Q -Vf MAX_TON BLOCK MAX_TON RMAX_TON -100mV -100mV R (4) VG2 (6) SR_GND Compulsion OFF TIME (2) (5) tMAX_ON Period allotted for G1 and G2 to avoid concurrent ON state at continuous mode operation. Compulsion OFF -6mV tMAX_ON Timer Start MAX_TON TIMER Compulsion OFF + Timer Start Compulsion ON TIME RESET_COMP Figure 2. The drive sequence in continuous mode operation (1) (2) (3) (4) (5) (6) Primary side FET = ON. Current I1 flows to the primary side FET. Secondary side drain voltage VDS2 rises. The VDS2 = VCC x 1.4 detects the rise edge of the threshold, MAX_TON timer start. Primary side FET = OFF. Current I2 flows through the Body Diode of the secondary side FET (OFF state). Secondary side drain voltage VDS2100mV by I2 Current, Secondary side FET=ON. Elapsed the set time in MAX_TON terminals, the secondary-side FET = compulsory OFF. Since the I2 current flows through the Body Diode, Vf voltage occurs. a capacitor C1 and a Moreover, in order to reduce as much as possible the influence of the switching noise, resistor R1 in series should be connected to the MAX_TON terminal. The capacitance should approximately be 1000pF, and the resistance value is recommended to be around 1k.This also serves as phase compensation of MAX_TON terminal and therefore should be connected. This function may be disabled by pulling up the MAX_TON terminal to VCC pin in quasi-resonant and current resonance applications which do not operate on continuous mode. The 1000pF and 1k resistor is also unnecessary. 6. AUTO SHUTDOWN Block The Auto Shutdown block automatically turns the synchronous rectification ON/OFF depending on the presence or absence of the DRAIN terminal pulse. Shutdown occurs if the input pulses on the DRAIN terminal has more than 200us between pulses. This stops the synchronous rectification operation. The IC will restart the synchronous rectification after it detects 256 occurrences of input pulses on the DRAIN terminal. 7. SHUNT REGULATOR Chip A high-accuracy shunt regulator with ultra-low consumption is used for controlling the output voltage of the AC/DC. Since the synchronous rectification and the shunt regulator are built in a completely different chip, GND separation is possible. Therefore, it becomes possible to place the shunt regulator on the secondary-side GND reference in the synchronous rectification applications in case of disposing the High Side FET. It can also be used as protection for the comparator, the secondary side OVP, FET overheat protection, etc. 8. PROTECTION Block When an abnormal condition is detected after the timer count is completed, the photo coupler from SH_OUT terminal is driven to stop the switching operation on the primary side. www.rohm.com (c) 2016 ROHM Co., Ltd.

MAX_TON Pin Setting A resistance value which is connected to the MAX_TON terminal is used to set the timer to force the GATE output OFF. (For detailed operation, please see "each block Operation / MAX_TON blocks") Set timer is proportional to the resistance value which can be set in the range of 56k to 300k. This IC is capable of an accuracy of 10us 6% at 100k. However, accuracy deteriorates as the resistance value gets further away from 100k. For example, 5.6s 0.9s at 56k, 30s 4.5s at 300k. (See graph below) 34.5u tTp P 30u Jitter G1 G1 Set the MAX_TON timer so that the FET of the primary side (G1) and the secondary side (G2) is not simultaneously ON 10.6u 10.0u 9.4u MAX_TON TIMER 56k 100k MAX_TON Resistor [ohm] 300k TMAX_ON tMAX_ON Compulsion OFF G2 G 2 6.5u 5.6u 4.7u Timer Start MAX_TON Timer [s] 25.5u Figure 18. Primary FET and Secondary FET Sequence at CCM Mode Figure 17. MAX_TON Timer vs MAX_TON Resistor(RMAX_TON) To prevent destruction due to surge current in continuous mode, set the MAX_TON timer before turning on the primary side FET (G1) to forcibly OFF the secondary side FET (G2). Regarding such variations, select a resistance value of MAX_TON terminal so that the MAX_ON timer setting time is less than one cycle in the primary side (TP > TMAX_ON). - The primary side of the maximum frequency = fMAX [Hz] - The primary side of the maximum frequency accuracy = fMAX [%] - The primary side of the jitter frequency = fJITTER [Hz] - Secondary side MAX_TON timer time = tMAX_ON - Secondary side MAX_TON timer time accuracy = tMAX_ON - Secondary side MAX_TON When the connection resistance accuracy = R 10000 [k][kHz] RMAX_TON[k] < (1+tMAX_ON[%]+R[%] +fMAX[%])x(fMAX[kHz]+fJITTER [kHz]) Frequency Variation Ratio 2. Maximum Frequency Value Calculation Example Primary side frequency 100kHz 5% Primary side jitter frequency 8kHz Secondary side MAX_TON timer accuracy = 7% Secondary side MAX_TON connection resistance accuracy = 1% 10000 [k][kHz] RMAX_TON [k] < = 81.94 [k] (1+5%+1%+7%)x(100kHz+8kHz) With these conditions, MAX_TON Resistor(RMAX_TON) should be set to 81k or less. In addition, it is recommended that the temperature characteristics of each component should also be taken into account. www.rohm.com (c) 2016 ROHM Co., Ltd. All rights reserved.

Flyback Application Circuit (Low Side FET) (1) VCC line may malfunction under the influence of switching noise. Therefore, it is recommended to insert a capacitor CVCC between the VCC and SR_GND terminal. (2) SH_IN terminal is a high impedance line. To avoid crosstalk, electrical wiring should be as short as possible and not in parallel with the switching line. (3) MAX_TON terminal has a 0.4V output. The external components of the MAX_TON terminal affects the forced OFF time due to switching. Thus, R1 and C1 should be connected to MAX_TON terminal as near as possible. It is also recommended to use an independent electrical wiring in connection with SR_GND terminal. (4) The synchronous rectification controller IC must accurately monitor the VDS generated in the FET. Accordingly, the electrical wiring between the DRAIN to DRAIN and SR_GND to SOURCE of the IC and FET respectively should be connected independently. (5) The SH_GND of the shunt regulator and the feedback resistors of VOUT are recommended to be connected to the GND of the output with an independent electrical wiring. (6) The DRAIN terminal is a 0100V switching line. Use a narrow wiring and connect as short as possible. (7) Use an independent wiring if connecting a snubber circuit between the DS of the FET. The connection of the transformer output and the SOURCE of the FET should be thick and short as possible. (8) Due to the DRAIN pin detects the small voltage, a malfunction which the switch turns ON/OFF caused by the surge voltage may occur. So that, the filters such as the ferrite bead are recommended for alleviating the surge voltage. (Note 6) Configuration example : LFB1 ( a ferrite bead for suppressing the surge voltage) : MMZ1608S202A D1 ( a schottky barrier diode) : RB751G-40 RDRAIN1 ( a filter resistor for the FET turn off ) : 0.3k - 2k RDRAIN2 ( a current limiting resistor to the DRAIN terminal) : 150 (Note 6) The value is not a guaranteed value, but for reference. Please choose the optimum values of the components after sufficient evaluations based on the actual application. www.rohm.com (c) 2016 ROHM Co., Ltd. All rights reserved. TSZ22111 * 15 * 001 17/22 TSZ02201-0F4F0A2BM1R0-1-2 20. Apr. 2016 Rev.002 BM1R00xxxF Operational Notes 1. Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC's power supply pins. 2. Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Except for pins the output and the input of which were designed to go below ground, ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. 5. Thermal Consideration Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the maximum junction temperature rating. 6. Recommended Operating Conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 7. Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 8. Operation Under Strong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 9. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC's power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 10. Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few. 11. Unused Input Terminals Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power supply or ground line. www.rohm.com (c) 2016 ROHM Co., Ltd. All rights reserved.

Regarding Input Pins of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example (refer to figure below): When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided.

Example of Monolithic IC Structure 13. Ceramic Capacitor When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with temperature and the decrease in nominal capacitance due to DC bias and others. 14. Area of Safe Operation (ASO) Operate the IC such that the output voltage, output current, and the maximum junction temperature rating are all within the Area of Safe Operation (ASO). 15. Thermal Shutdown Circuit(TSD) BM1R00121F - BM1R00150F (Auto Restart Protection Series) This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always be within the IC's maximum junction temperature rating. If however the rating is exceeded for a continued period, the junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below the TSD threshold, the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. BM1R00001F - BM1R00030F (Latch Protection Series) This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always be within the IC's maximum junction temperature rating. If however the rating is exceeded for a continued period, the junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. The IC should be powered down and turned ON again to resume normal operation because the TSD circuit keeps the outputs at the OFF state even if the TJ falls below the TSD threshold. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. www.rohm.com (c) 2016 ROHM Co., Ltd.
