Universal High Voltage LED Driver
with Integrated MOSFET
General Description This demonstration board utilizes the AL9901 high voltage PWM LED Buck controller with integrated MOSFET providing a cost effective solution for offline high brightness LED applications. This user‐
friendly evaluation board provides users with quick connection to their different types LEDs string. The demonstration board can be modified to adjust the LED output current (140mA) and the number of series connected LEDs that are driven. Key Features 

Dimmable by R2, remove R2 to allow PWM Dimming input. 2. Ensure that the AC source is switched OFF or disconnected. 3. Connect the AC line wires of power supply to “AC+ and AC‐” on the left side of the board. 4. Connect the anode wire of external LED string to LED+ output test point. 5. Connect the cathode wire of external LED string to LED‐ output test point. 6. Turn on the main switch. LED string should light up. AL9901EV2 REV1
