In order to counteract the possible effect of input line inductance on the stability of the converter, the use of decoupling capacitors placed in close proximity to the converter input pins is recommended. This will ensure stability of the converter and reduce input ripple voltage. Although low ESR Tantalum or other capacitors should typically be adequate, very low ESR capacitors (ceramic, over 100F) are recommended to minimize input ripple voltage. The converter itself has on-board internal input capacitance of 3F with very low ESR (ceramic). FPMR12TR7505*A ESR ESR(100F )ESR3F The FPMR12TR7505*A is capable of stable operation with no external capacitance on the output. To minimize output ripple voltage, the use of very low ESR ceramic capacitors is recommended. These capacitors should placed in close proximity to the load to improve transient performance and to decrease output voltage ripple. FPMR12TR7505*A ESR ESR Note that the converter does not have a SENSE pin to counteract voltage drops between the output pins and the load. The impedance of the line from the converter output to the load should thus be kept as low as possible to maintain good load regulation. The ON/OFF pin (pin 5) can be used to turn the converter on or off remotely using a signal that is referenced to GND (pin 3), as shown in Fig. A. Two remote control options are available, corresponding to negative and positive logic. In the negative logic option, to turn the converter on Pin 5 should be at logic low or left open, and to turn the converter off Pin 5 should be at logic high or connected to Vin. In the positive logic option, to turn the converter on Pin 5 should be at logic high, connected to Vin or left open, and to turn the converter off Pin 5 should be at logic low. ON/OFF(5)A(3) ON/OFF 2 ON5Low OFF5HighVin ON5High VinOFF5Low Pin 5 is internally pulled-down. A TTL or CMOS logic gate, or an open collector/drain transistor can be used to drive Pin 5. When using an open collector/ drain transistor, a pull-up resistor, R*=75k, should be connected to Vin (See Fig.A). The device driving Pin 5 must be capable of: (a) Sinking up to 0.2mA at low logic level (0.8V) (b) Sourcing up to 0.25mA at high logic level (2.3-5V) (c) Sourcing up to 0.75mA when connected to Vin ON/OFFTTL CMOS ON/OFF A75k Vin(A) ON/OFF (a) 0.8VLow0.2mA (b) 2.3V-5VHigh0.25mA (c) Vin0.75mA Vin Vout R* On/Off Vin GND Load TRIM Control Signal Fig. A: Circuit configuration for remote ON/OFF http://www.fdk.co.jp Page 5 of 26 Ver 2.1 Jul. 26, 2007 Delivering Next Generation Technology Series FPMR12TR7505*A 6-14Vdc Input, 5A, 0.7525-5.5Vdc Output Table 1: Trim Resistor Value The Closest VO-REG [V] RTRIM [k] Standard Value [k] 0.7525 Open 1.0 41.42 41.2 1.2 22.46 22.6 1.5 13.05 13.0 1.8 9.02 9.09 2.0 7.42 7.50 2.5 5.01 4.99 3.3 3.12 3.09 5.0 1.47 1.47 5.5 1.21 1.21 Output Voltage Programming (Pin 2) The output voltage of the FPMR12TR7505*A converter can be programmed from 0.7525V to 5.5V by using an external resistor or a voltage source FPMR12TR7505*A 0.7525V5.5V External Resistor An external trim resistor, RTRIM, should be connected between TRIM (pin 2) and GND (pin 3); see Fig. B.

Standard 1% or 0.5% resistors may suffice for most applications; however, a tighter tolerance can be obtained by using two resistors in series insteed of one standard value resistor. Table 1 lists calculated values of RTRIM for common output voltages. For each value of RTRIM, Table 1 also shows the closest available standard resistor value. RTRIM 1%0.5% 12 Table 1 Table 1 External Voltage Source To program the output voltage using an external voltage source, a voltage, VCTRL, should be applied to the TRIM pin.

It will then turn on automatically when the input voltage reaches typically 5.5V. TYP4.4V TYP5.5V Output Over-Current Protection (OCP) The converter is self-protected against over-current and short circuit conditions. On the occurrence of an over-current condition, the converter will enter a pulseby-pulse hiccup mode. On the removal of the overcurrent or short circuit condition, Vout will return to the original value (auto-reset). -- HICCUP Vout() Over-Temperature Protection (OTP) The converter is self-protected against overtemperature conditions. In case of overheating due to abnormal operation conditions, the converter will turn off automatically. It will turn back on automatically once it has cooled down to a safe temperature (autoreset). () Safety Requirements The converter meets North American and International safety regulatory requirements per UL60950 and EN60950. The converter meets SELV (safety extralow voltage) requirements under normal operating conditions in that the output voltages are ELV (extralow voltage) when all the input voltages are ELV. Note that the converter is not internally fused: to meet safety requirements, a fast acting in-line fuse with a maximum rating of 7.5A must be used in the positive input line. http://www.fdk.co.jp UL60950EN60950 SELV ELVELV 7.5A Characterization Overview The converter has been characterized for several operational features, including thermal derating (maximum available load current as a function of ambient temperature and airflow), efficiency, power dissipation, start-up and shutdown characteristics, ripple and noise, and transient response to load stepchanges. Figures showing data plots and waveforms for different output voltages are presented in the following pages. The figures are numbered as Fig.*V-#, where *V indicates the output voltage, and # indicates a particular plot type for that voltage. For example, Fig *V-2 is a plot of efficiency vs. load current for any output voltage *V. Fig *V-#*V# Fig *V-2*V Test Conditions To ensure measurement accuracy and reproducibility, all thermal and efficiency data were taken with the converter soldered to a standardized thermal test board. The thermal test board was mounted inside FDK's custom wind tunnel to enable precise control of ambient temperature and airflow conditions. FDK Page 7 of 26 Ver 2.1 Jul. 26, 2007 Delivering Next Generation Technology Series FPMR12TR7505*A 6-14Vdc Input, 5A, 0.7525-5.5Vdc Output The thermal test board comprised a four layer printed circuit board (PCB) with a total thickness of 0.060". Copper metallization on the two outer layers was limited to pads and traces needed for soldering the converter and peripheral components to the board. The two inner layers comprised power and ground planes of 2 oz. copper. This thermal test board, with the paucity of copper on the outer surfaces, limits heat transfer from the converter to the PCB, thereby providing a worst-case but consistent set of conditions for thermal measurements. 0.060"(1.6mm)4PCB 2 270m PCB It is advisable to check the converter temperature in the actual application, particularly if the application calls for loads close to the maximums specified by the derating curves. IR thermography or thermocouples may be used for this purpose. In the latter case, AWG#40 gauge thermocouples are recommended to minimize interference and measurement error. An optimum location for placement of a thermocouple is indicated in Fig. C. AWG40 C Thermal Derating Figs *V-1 show the maximum available load current vs. ambient temperature and airflow rates. Ambient temperature was varied between 30C and 85C, with airflow rates from NC(50 LFM) to 400 LFM (0.25m/s to 2.0m/s). The converter was mounted horizontally, and the airflow was parallel to the long axis of the converter, going from pin 1 to pin 5. *V-1 NC(50LFM)400LFM3085 15 FDK Original Wind Tunnel The maximum available load current, for any given set of conditions, is defined as the lower of: (i) The output current at which the temperature of any component reaches 120C, or (ii) The current rating of the converter (5A) A maximum component temperature of 120C should not be exceeded in order to operate within the derating curves. Thus, the temperature at the thermocouple location shown in Fig. C should not exceed 120C in normal operation. (i) 120 (ii) (5A) Test Chamber FDK's custom wind tunnel was used to provide precise horizontal laminar airflow in the range of 50 LFM (equivalent to natural convection, NC) to 400LFM, at ambient temperatures between 30C and 85C.
