■ Description

FA3629AV is a Power IC which includes DC-DC converter controller and Nch-power MOSFET. This IC can directly drive 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

• 40V CDMOS Process:

Built-in 0.3Ω Nch-Power MOSFET(ch1, open drain)

• 3-channels PWM Control:

2 boost circuits(ch1, ch2), 1 inverting circuit (ch3)

• Adjustable soft start time and maximum duty cycle

• Built-in timer latch for short circuit protection:

Delay time = 216 / (switching frequency)

• Built-in protection functions: Overcurrent limit for MOSFET,

overheat protection, undervoltage lockout

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

• Package: TSSOP-16(Thin and small)

■ Applications

• Power supply for general equipment
