HA16108FP

PWM Switching Regulator for High-performance Voltage Mode Control

Hitachi -> Renesas Electronics 

HA16107P/FP, HA16108P/FP

PWM Switching Regulator for

High-performance Voltage Mode Control

Description

The IC products in this series are primary control switching regulator control IC’s appropriate for obtaining

stabilized DC voltages from commercial AC power.

These IC’s can directly drive power MOS FET’s, they have a timer function built in to the secondary

overcurrent protection, and they can perform intermittent operation or delayed latched shutdown as

protection operations in unusual conditions. They can be used to implement switching power supplies with

a high level of safety due to the wide range of built-in functionality.

Functions

• 6.45 V reference voltage

• Triangle wave generator

• Error amplifier

• Under voltage lockout protector

• PWM comparator

• Pulse-by-pulse current limitting

• Timer-latch current limitting (HA16107)

• ON/OFF timer function (HA16108)

• Soft start and quick shutdown

• Output circuit for power MOS FET driving
