■ Description

The FA7630CP(E) is dual channel PWM-type switching power supply control IC.

This IC can drive Pch-MOSFET directly and is optimum for large power DC-DC converter.

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

• Dual channel PWM-type switching power supply control

• ±2.6% (VREF) and ±3% (VB) reference voltage

• Low voltage operation (Vcc: 5 to 20V)

• Drive circuit for connecting a Pch-MOSFET

• Overload cutoff circuit with timer latch circuit

• Soft start circuit

• Undervoltage lockout function (UVLO)

• Pulse-by-pulse overcurrent limiting function

• Output ON/OFF control function for each channel

• Master-slave synchronized operation without external components

• Maximum operating frequency is 500kHz
