Description
The FA13844N is a CMOS current mode control IC for off-line and DC-to-DC converters. It is part of the FA1384X series, which is designed to reduce start-up circuit loss and provide high efficiency power supplies through changes in the CMOS fabrication process. This IC can drive a power MOSFET directly, and allows for the design of a high-performance, compact power supply with minimal external components.
Specifications and features
