Description

The FA7622CP(E) is a DC-DC converter IC that can directly drive a power MOSFET. This IC has all the necessary protection functions for a power MOSFET. It is optimum for a portable equipment power supply which uses low-voltage input to output comparably large power.

Features

• Drive circuit for connecting a power MOSFET (Io = ±600mA)

• Built-in voltage step-up circuit to drive a power MOSFET gate: A converter circuit requires only an N-channel power MOSFET.

• Dual control circuit

• Overcurrent limiting circuit

• Overload cutoff circuit with timer and latch circuit

• ON/OFF control pin

• Wide operating range: 3.6 to 28V

• High-frequency operation: up to 1MHz

• 20-pin package (DIP/SSOP)

Applications

• Battery power supply for portable equipment
