Product 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.
