HA16114P Datasheet Switching Regulator for Chopper Type DC/DC Converter

Manufacturer: Hitachi Semiconductor (now Renesas)

General Description

The HA16114P/FP/FPJ and HA16120FP/FPJ are single-channel PWM switching regulator controller ICs suitable for chopper-type DC/DC converters.

Integrated totem-pole output circuits enable these ICs to drive the gate of a power MOSFET directly.

The output logic of the HA16120 is designed to control a DC/DC step-up (boost) converter using an N-channel power MOS FET.

Overview

HA16114P/PJ/FP/FPJ, HA16120FP/FPJ Switching Regulator for Chopper Type DC/DC.

Key Features

  • include a pulse-by-pulse current limiter that can reduce the width of individual PWM pulses, and an intermittent operating mode controlled by an on-off timer. Unlike the conventional latched shutdown function, the intermittent operating function turns the IC on and off at controlled intervals when pulse-by-pulse current limiting continues for a programmable time. This results in sharp vertical settling characteristics. Output recovers automatically when the overcurrent condition subsides. Using.
