s FUNCTIONAL DESCRIPTION
1. Switching Regulator Functions
(1) Reference voltage circuit (Ref) The reference voltage generator uses the voltage supplied from the VCC pin (pin 18) to generate a temperaturecompensated, stable voltage (about 2.50 V) as the reference supply voltage for the IC's internal circuitry. The reference voltage can be output, up to 1 mA, to an external device through the VREF pin (pin 1). (2) Triangular wave oscillator (OSC) The triangular wave oscillator generates a triangular waveform with a timing capacitor and a timing resistor respectively connected to the CT pin (pin 3) and RT pin (pin 2). The triangular wave is input to the PWM comparator in the IC while it can also be supplied to an external device through the CT pin. In addition, the oscillator can be used for external synchronization, where it generates a triangular wave synchronous to the input signal from the SYNC pin (pin 4). (3) Error amplifiers (Error Amp. 1, 2) The error amplifiers detect the output voltage from the switching regulator and outputs the PWM control signal. It supports a wide range of in-phase inputs from 0 V to "VCC - 0.9 V". An arbitrary loop gain can be set by connecting a feedback resistor and capacitor from the FB1 pin (pin 6) [FB2 pin (pin 15)] to the -IN1 pin (pin 7) [-IN2 pin (pin 14)] of the error amplifier, enabling stable phase compensation to the system. (4) Current detector amplifier (Current Amp.) The current detector amplifier provides 25 x amplification of the voltage drop between the two ends of the output sensor resistor (RS) in the switching regulator, that occurs due to the flow of the charging current. At the same time, the amplifier converts the voltage to the GND-reference voltage level and outputs it to the COUT pin (pin 12). It can also control the charging current in combination with the error amplifier circuit. (5) Power control circuit (CTL) The power control circuit can control turning on and off the power supply through the CTL pin (pin 17). (Supply current in standby mode: About 0 A) Depending on the voltage level of the PWM Comp. input pin, the OUT pin (pin 19) may become "L" level during discharging of the VREF voltage after the CTL pin is turned off with a capacitor connected to the VREF pin. The power control circuit contains a function for fixing the OUT output pin to the "H" level when CTL = "L" and VREF = "H", preventing inadvertent "L" level output after turning the CTL pin off. (6) PWM comparator circuit (PWM Comp.) The PWM comparator circuit is a voltage-pulse width converter for controlling the output duty of the error amplifiers (Error Amp. 1, 2) depending on their output voltage. The PWM comparator circuit turns on the external output transistor during the interval in which the triangular wave voltage level is lower than the voltage level at both of the error amplifier output pins (FB1 pin (pin 6), FB2 pin (pin 15)) and the DTC pin (pin 16). (7) Output circuit (Out) The output circuit uses a totem-pole configuration, capable of driving an external P-channel MOS FET and PNP transistor. It can also control the output sink current with a resistor connected between the VE pin (pin 20) and the GND pin (pin 11).
2. Protection Functions
(1) Low input voltage malfunction preventive circuit (ULVO) The transient state or a momentary decrease in supply voltage, which occurs when the power supply is turned on, may cause errors in the control IC, resulting in breakdown or degradation of the system. The low input voltage malfunction preventive circuit detects the internal reference voltage level according to the supply voltage 13
MB3832A
and turn off the external output transistor to make dead time 100%. The circuit restores voltage supply when the supply voltage reaches its threshold voltage. (2) Timer-latch short-circuit protection circuit (SCP Comp., SR Latch) The latch circuit detects the output voltage levels of the error amplifiers. When the output voltage levels of the two error amplifiers reach about 2.1 V at the same time, the timer circuit is actuated to start charging the external capacitor connected to the CSCP pin (pin 5). If the error amplifier outputs are not restored to the normal voltage range before the capacitor voltage reaches about 0.7 V, the latch circuit is actuated to fix the output pins (OUT) at the "H" level. To reset the actuated protection circuit, turn the power supply on back.

s METHOD OF SETTING FOR EXTERNAL SYNCHRONOUS OSCILLATION
For external synchronous oscillation, connect a timing capacitor (CT), a timing resistor (RT), and an external sync signal to the CT, RT, and SYNC pins, respectively. In this case, select the CT and RT so that the oscillation frequency is 5% to 10% lower than the frequency of the external synchronous signal excluding the setting error of the oscillation frequency. The duty cycle (T1/T) of the external sync signal must be set within a range from 10% to 90%.

s METHODS OF SETTING THE DEAD TIME AND SOFT START
1. Dead Time
When the device is set for step-up inverted output based on the flyback method, the output transistor is fixed to a full-ON state (ON duty = 100%) when the power supply is turned on. To prevent this problem, you may determine the voltage at the DTC pin (pin 16) from the VREF voltage so you can set the output transistor's dead time (maximum ON-duty period) as shown in Figure a below. When the voltage at the DTC pin (pin 16) is higher than the triangular wave output voltage from the oscillator, the output transistor is turned off. The dead time calculation formula assuming that triangular wave amplitude . 0.6 V and triangular wave minimum voltage . 1.3 V is given below. = = . . = Duty (ON) . . R2 Vdt - 1.3 V x 100 [%], Vdt = x VREF 0.6 V R1 + R2
When the DTC pin is not used, connect it directly to the VREF pin. * Figure a Setting the dead time * Figure b Not setting the dead time

2. Soft Start
To prevent surge currents when the IC is turned on, you can set a soft start using the DTC pin (pin 16). You can also set a soft start along with the dead time by making connections as shown in Figure d below. * Figure c Setting a soft start * Figure d Setting the dead time and a soft start
