Soft Start At power on, the capacitor CPE connected to the SCP pin (pin 2) starts charging. The PWM comparator compares the soft start setting voltage as a proportion of the voltage at the SCP pin with the sawtooth waveform. The comparison controls the ON duty of the OUT pin (pin 5), causing the soft start operation. On completion of soft start operation, the voltage at the SCP pin stays low, the soft start setting voltage stays high, and the circuit enters the output short circuit detection wait state. Soft start time (The time until the output ON duty reaches approximately 50%) tS [s] 0.35 x CPE [F] 2. Short Circuit Protection If the switching regulator output suddenly drops due to load effect, the error amplifier output (FB pin (pin 8)) is fixed at VOM+ and capacitor CPE starts charging. When the voltage at the SCP pin reaches approximately 0.8 V, the OUT pin (pin 5) is set low and the SCP pin (pin 2) stays low. Once the protection circuit operates, the circuit can be restored by resetting the power supply. * Short circuit detection time tPE [s] 0.8 x CPE [F] 7 MB3800 TYPICAL CHARACTERISTICS Input threshold voltage vs. Supply voltage T a = +25C R B = 390 10 1.0 Input threshold voltage V T (V) Average supply current I CC (mA) Average supply current vs. Supply voltage 8 6 4 2 0 0 4 8 12 16 0.8 0.6 0.4 0.2 0 20 T a = +25C 0 4 Input threshold voltage vs. Supply voltage 0.8 0.6 0.4 0.2 0 High level output voltage V OUT (V) T a = +25C 0 1.0 2.0 3.0 4.0 5.0 10 V CC = 2 V 5 0 -5 -10 -15 -40 -20 0 +20 +40 +60 +80 Low level output 1.6 1.2 0.8 0.4 -10 Input threshold voltage variation ratio vs. Operating ambient temperature High level output V CC = 2 V R B = 390 T a = +25C 0 20 Operating ambient temperature T a (C) 2.0 0 16 Supply voltage V CC (V) -20 -30 -40 High level output current IOUT (mA) -50 Low level output voltage V OUT (mV) Input threshold voltage V T (V) 1.0 12 Supply voltage V CC (V) Input threshold voltage variation ratio V T/V T (%) Supply voltage V CC (V) 8 +100 V CC = 2 V R B = 390 T a = +25C 500 400 300 200 100 0 0 20 40 60 80 100 Low level output current IOUT (mA) (Continued) 8 MB3800 -50 -40 V CC = 2 V V OUT = 0.9 V T a = +25C -30 -20 -10 0 -0.4 0 -0.8 -1.2 -1.6 BR/CTL pin input voltage vs. BR/CTL pin input current BR/CTL pin input voltage V BR (mV) Output source current IOUT (mA) Output source current vs. BR/CTL pin input current 500 400 300 200 100 0 -2.0 V CC = 2 V T a = +25C 0 BR/CTL pin input current I BR (mA) -0.4 -0.8 -1.2 -1.6 -2.0 BR/CTL pin input current I BR (mA) Oscillation frequency vs.Timing resistor Average supply current vs. BR/CTL pin input current 5.0 V CC = 2 V T a = +25C Oscillation frequency f OSC (Hz) Average supply current I CC (mA) 1M 4.0 3.0 2.0 1.0 0 -20 0 -40 -60 -80 500 k 200 k 100 k C T = 1000 pF 50 k 20 k C T = 10000 pF 10 k 5k 2k 20 k 10 k 5k Timing resistor R T () Frequency variation ratio vs. Operating ambient temperature Frequency variation ratio vs. Supply voltage 10 10 C T = 270 pF R T = 3.0 k Ta = +25C 5 Frequency variation ratio f/f (%) Frequency variation ratio f/f (%) 2k 1k -100 BR/CTL pin input current I BR (A) 0 -5 -10 -15 V CC = 2 V T a = +25C C T = 100 pF 0 2 4 6 8 10 12 Supply voltage V CC (V) 14 16 V CC = 2 V C T = 270 pF R T = 3.0 k 5 0 -5 -10 -15 -40 -20 0 +20 +40 +60 +80 +100 Operating ambient temperature T a (C) (Continued) 9 MB3800 (Continued) Maximum duty cycle vs. Oscillation frequency V CC = 2 V C T = 270 pF Ta = +25C Maximum duty cycle t DUTY (%) 100 80 60 40 20 0 10 k 100 k 1M Oscillation frequency f OSC (Hz) Output pin voltage and current waveforms (reference data) 2V (V) 6 V CC = 2 V C T = 270 pF R T = 1.0 k 4 V OUT 2 0 (mA) 50 I OUT 0 -50 10 mV 0 200 ns 0.4 0.8 1.2 1.6 2.0 t(s) Note: The OFF delay time of V OUT depends on the characteristics of the external transistor.

Switching Regulator Function (1) Reference voltage circuit The reference voltage circuit generates a temperature-compensated reference voltage (1.25V) from voltage supplied from the VCC pin (pin 3). In addition to providing the reference voltage for the switching regulator, the circuit also sets the idle period. (2) Sawtooth wave oscillator The sawtooth oscillator generates a sawtooth wave (up to 1 MHz) that is stable with respect to the supply voltage and temperature. The capacitor and resistor that set the oscillation frequency are connected to the OSC pin (pin 7). (3) Error amplifier (Error Amp) The error amplifier detects the output voltage of the switching regulator and outputs the PWM control signal. The voltage gain is fixed, and connecting a phase compensation capacitor to the FB pin (pin 8) provides stable phase compensation for the system. (4) PWM comparator (PWM Comp.) The voltage comparator has one inverting and three non-inverting inputs. The comparator is a voltage/pulse width converter that controls the ON time of the output pulse depending on the input voltage. The output level is high (H) when the sawtooth wave is lower than the error amplifier output voltage, soft start setting voltage, and idle period setting voltage. (5) Output circuit The output circuit has a totem pole type configuration and can drive an external NPN transistor directly. The value of the ON/OFF current can be set by a resistor connected to the BR/CTL pin (pin 4). 2. Power Supply Control Function Stand-by mode (supply current 1 A or less) can be set by connecting the BR/CTL pin (pin 4) to VCC or by making the pin open circuit. SW Mode OFF Stand-by mode ON Operating mode MB3800 4 BR/CTL RB SW 11 MB3800 3. Other Functions (1) Soft start and short circuit detection Soft start operation is set by connecting capacitor CPE to the SCP pin (pin 2). Soft start prevents a current spike on start-up. On completion of soft start operation, the SCP pin (pin 2) stays low and enters the short circuit detection wait state. When an output short circuit occurs, the error amplifier output is fixed at VOM+ and capacitor CPE starts charging. After charging to approximately 0.8 V, the OUT pin (pin 5) is set low and the SCP pin (pin 2) stays low. Once the protection circuit operates, the circuit can be restored by resetting the power supply. (See " HOW TO SET THE TIME CONSTANT FOR SOFT START AND SHORT CIRCUIT DETECTION".) (2) Circuit to prevent malfunction at low input voltage Transients when powering on or instantaneous glitches in the supply voltage can lead to malfunction of the control IC and cause system damage or failure. The circuit to prevent malfunction at low input voltage detects a low input voltage by comparing the supply voltage to the internal reference voltage. On detection, the circuit fixes the OUT pin (pin 5) to low. The system recovers when the supply voltage rises back above the threshold voltage of the malfunction prevention circuit.
