HA16666P/FP
600kHz PWM Controlled Switching
Regulator
Description
The HA16666P/FP is a voltage mode PWM (pulse width modulation) control IC for switching
regulator control.
It can drive a power MOS FET efficiently on 600 kHz.
Its stanby current is 0.
3 mA (max), and it is used as the primary control power supply.
