HA16121FPJ Datasheet Switching Regulator For Chopper Type DC/dc Converter

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HA16116FP/FPJ, HA16121FP/FPJ Switching Regulator for Chopper Type DC/DC.

General Description

HA16116FP/FPJ and HA16121FP/FPJ are dual-channel PWM switching regulator controller ICs for use in chopper-type DC/DC converters.

This IC series incorporates totem pole gate drive circuits to allow direct driving of a power MOS FET.

The output logic is preset for booster, step-down, or inverting control in a DC/DC converter.

Key Features

  • Wide operating supply voltage range.
  • (3.9 V to 40.0 V) Wide operating frequency range (600 kHz maximum operation) Direct power MOS FET driving (output current ±1 A peak in maximum rating) Pulse-by-pulse overcurrent protection circuit with intermittent operation function (When overcurrent state continues beyond time set in timer, the IC operates intermittently to prevent excessive output current. ).
  • Grounding the ON/OFF pin turns the IC off, sav.
