FA13844 General Description

The FA1384X series are CMOS current mode control ICs for off-line and DC-to-DC converters.

These ICs can reduce start-up circuit loss and are optimum for high efficiency power supplies because of the low power dissipation achieved through changes in the CMOS fabrication process.

These ICs can drive a power MOSFET directly.

The high-performance, compact power supply can be designed with minimal external components .
