FA3621F
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: 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
• Wide range of operation frequency: 50kHz to 1MHz
• Package: LQFP-48(Thin and small)
s Application
• VTR-camera, digital-steel-camera and portable equipment
