CMOS IC

For Switching Power Supply Control

s 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.

s 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: 10

µA(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

• Wide range of operation frequency: 50kHz to 1MHz

• Package: LQFP-48(Thin and small)

s Application

• VTR-camera, digital-steel-camera and portable equipment
