EV4059-S-00A Evaluation Kit 90VAC to 265VAC, 21V/350mA Single-Stage Deep PWM Dimming Solution Evaluation Board
The EV4059-S-00A evaluation board is designed to demonstrate the capabilities of the 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 optocoupler significantly simplifies LED driver design. The MP4059 integrates power factor correction and works in valley switching mode to achieve high efficiency.
The EV4059-S-00A adopts flyback topology to drive a 21V LED.
