Description

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

This FA7630CP(E) IC can drive Pch-MOSFET directly and is optimum for large power DC-DC converter.

This FA7630CP(E) 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.
