Product 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.
