FA3621F - For Switching Power Supply Control

General Description

FA3621F is a control IC for 6-channel DC-DC converter.

This IC can directly drive a Nch/Pch-MOSFET.

This IC is suitable to reduce converter size because it has many functions in a small package LQFP-48.

Key Features

  • 6-channel PWM control with MOSFET direct driving : 5-channel for Pch-MOSFET, 1channel for Nch-MOSFET.
  • Low input voltage: 4.5V to 20V.
  • ±1.5% high accuracy bandgap reference.
  • Low power consumption by means of CDMOS Standby mode: 10µA(max. ) Operating mode: 6mA(max. ).
  • Soft start function for each channel.
  • ON/OFF function for each channel.
  • Timer latch for short protection.
  • Overheat protection.
  • Undervoltage lockout.
