Offline PFC controller, boundary conduction mode
Session Titefor popup
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.
