Product Description

The MP44014-A is a boundary conduction mode PFC controller that provides simple and high-performance active power-factor correction using minimum 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 the 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 the disable function reduces the power consumption, resulting in excellent efficiency performance. The MP44014-A is available in a SOIC-8.
