DESCRIPTION

The MP44010 is a boundary conduction mode

PFC controller which can provide simple and

high performance active power factor correction

using minimum external components.

The output voltage is accurately regulated by a

high performance voltage mode amplifier with

an accurate internal voltage reference.

The precise adjustable output over-voltage

protection

greatly

enhances

the

system

reliability.

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

can eliminate the external R/C filter.

The extremely low start-up current, quiescent

current and the disable function can reduce the

power consumption and result in excellent

efficiency performance.

The MP44010 is available in SOIC8 and DIP

packages.
