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.

The EV44010-S+4688-N-01A is an evaluation board of MP44010 and MP4688 for 30W LED lighting driver.
The EV44010-S+4688-N-01A contains 2 stages: the first stage is Flyback PFC using MP44010 which can provide high power factor; the second stage is 2-channel DC/DC using MP4688 and every channel can deliver 15W/350mA for LED.
MP44010 is a boundary conduction mode PFC controller which can provide simple and high performance active power factor correction using minimum external components.
MP4688 is a high voltage input step-down switching regulator to deliver a constant current to LED. The hysteresis current mode control is applied for very fast response.
The EV44010-S+4688-N-01A can meet the Class C standard of IEC61000-3-2 and EN55015 standard.
