DESCRIPTION

The MP44014 is a boundary conduction mode

PFC controller that provides simple, high-

performance, active power factor correction

using minimal external components.

The output voltage is regulated accurately by a

high-performance voltage mode amplifier with

an accurate internal voltage reference.

The precise, adjustable output over-voltage

protection greatly enhances system reliability.

The on-chip R/C filter on the current sense pin

can potentially eliminate the external R/C filter.

The extremely low start-up current, quiescent

current, and disable function reduces power

consumption, resulting in excellent efficiency

performance.

The MP44014 is available in a SOIC-8 package.
