Monolithic Power Systems MP44010

Boundary Mode PFC Controller

Overview

TopologyBoost Converter
Input voltage85-265 V
Output 10.7 A
IC revision1.11

Description

The MP44010 is a boundary conduction mode PFC controller which can provide simple and high performance active power factor correctionusing 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 excellentefficiency performance.

The MP44010 is available in SOIC8 and DIP packages.
