FA7703/04
Description
FA7703/04 are the PWM type DC-DC converter control ICs with 2ch output that can directly drive power
MOSFETs. FA7703/04 feature CMOS devices with high breakdown voltage and also low power
consumption are achieved. By means of their small and thin package (1.1mm max.), and high frequency
operation (to 1MHz), FA7703/04 are completely suitable for the use of very small DC-DC converters.
Besides, you can select a Pch or Nch type of MOSFET directly driven by FA7703/04, and also you can
practically design any kind of DC-DC converter circuit like a boost converter, a buck converter, a inverting
converter, a fly-back converter, and so on.
1. Features
