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

•

High-speed switching;

tr = 80 ns (15 V amplitude)

tf = 40 ns (15 V amplitude)

•

Low power dissipation;

0.3 mA max in standby state

12 mA max in operation state (V_IN= 15 V)

Dual-slope highly accurate dead-band duty setup circuit; Setup accuracy Du = ±3% (max)

Wide output pulse width control range; 0 to 75%
