Regulated-voltage output pin (5V output)
Connect a capacitor (about 0.1µF) between this pin and
ground for stabilization.
Power pin (PWM oscillation, PWM comparator, VCTL amp).
Normally connect to VREG.
Voltage detection pin for low-voltage protection. To detect
the supply voltage of 5 V or more, connect the zenor diode
in series to set the detection voltage.
Power pin (V
voltage of 12 V or more.
12 V is generated at the 12 REG pin. To use the 12REG
pin, connect this pin to V
V
PWM waveform comparator pin. Normally used in the open
condition. By inputting the voltage directly into this pin, the
output duty can be controlled without using the VCTL amp.
