FA13842,13843,13844,13845

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 .

• Pin-for-pin compatible with UC384X

Note:

Pins are fully compatible, but characteristics are not.

When our ICs are applied to a power supply circuit

designed for other manufactures' 384X series, the

characteristics and safety features of the power supply

must be checked.
