EV44011HS+4689DN-00A
Flyback PFC+2 Channel DC/DC
30W Offline WLED Driver
DESCRIPTION
FEATURES
The EV44011HS+4689DN-00A is an evaluation
board of MP44011 and MP4689 for 30W LED
lighting driver.





The EV44011HS+4689DN-00A contains 2
stages: the first stage is Flyback PFC using
MP44011; the second stage is 2-channel
DC/DC using MP4689 and every channel can
deliver 15W/350mA for LED.
MP44011 is a boundary conduction mode PFC
controller with internal harmonic injection
comparing with MP44010 which is a traditional
Boundary mode PFC controller, MP44011 can
bring benefits, such as decreased output cap of
Flyback PFC and reduced transformer core size.
(Please see details in MP44011 datasheet.)
MP4689 is a high voltage step-down switching
regulator to deliver a constant current to LED.
The hysteresis current mode control is applied
for very fast response.
The EV44011HS+4689DN-00A can meet the
EN55015 standard.

QUICK START GUIDE
1. Preset AC input voltage between 85V and 265V. Then turn off AC power supply.
2. Connect the LED string to the LED+ and LED- pins on each channel.
3. Connect the Line and Neutral terminals of the power supply output to AC input.
4. Turn the power supply on. The board will automatically startup.
