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.
Functions
* * * * * * * * * +5 V reference voltage circuit Triangular waveform oscillator PWM comparator Output circuit (Totem pole output) Overcurrent protection circuit (with one-pulselatch mode) Undervoltage lockout protectoin circuit Soft start and quick shutdown function Remote control function Comparator with internal 1.3 V reference voltage
Features
