Monolithic Power Systems MP4059 | Demoboard EV4059-S-00A

Beschreibung

The EV4059-S-00A Evaluation Board is designed to demonstrate the capabilities of MP4059. The MP4059 is a single power stage and PFC controller targeting at LED deep dimming applications. It can regulate a constant current to an LED load over a 1% to 100% dimming range without flicker or shimmer. It is a primary side controller without any secondary side feedback components and the opto-coupler to significantly simplify LED driver design. The MP4059 integrates power factor correction and works in valley switching mode to achieve high efficiency
