■ Description

FA3630V is a DC-DC converter controller. 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 TSSOP.

■ Features

• Low input voltage: 2.5V to 6.5V

• 2-channels PWM control: Rail-to-rail output

Output impedance of output stage = 3.5Ω (typ.)

Nch-MOSFET driving (Ch1)

Nch/Pch-MOSFET driving (Ch2)(selected by SEL pin)

• Low power consumption: 0.7mA (typ.)

• ON/OFFcontrol: Standby current= 0.1µA (typ.)

• ±2 high accuracy reference voltage

• Adjustable soft start time and maximum duty cycle

• Adjustable built-in timer latch for short circuit protection

• Wide range of operation frequency: 100kHz to 1MHz

• Package: TSSOP-16 (Thin and small)

■ Applications

• Power supply for general equipment
