■ HOW TO SET THE TIME CONSTANT FOR SOFT START AND SHORT CIRCUIT
DETECTION
1. 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 × CPE [µF]
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 × CPE [µF]

■ FUNCTIONAL DESCRIPTION
1. 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 µA or less) can be set by connecting the BR/CTL pin (pin 4) to VCC or by making
the pin open circuit.

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.

■ NOTES ON USE
• Take account of common impedance when designing the earth line on a printed wiring board.
• Take measures against static electricity.
- For semiconductors, use antistatic or conductive containers.
- When storing or carrying a printed circuit board after chip mounting, put it in a conductive bag or container.
- The work table, tools and measuring instruments must be grounded.
- The worker must put on a grounding device containing 250 kΩ to 1 MΩ resistors in series.
• Do not apply a negative voltage
- Applying a negative voltage of −0.3 V or less to an LSI may generate a parasitic transistor, resulting in
malfunction.
