Universal High Voltage LED Driver
General Description
This demonstration board utilizes the
AL9910A high voltage PWM LED Buck
controller 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.

Quick Start Guide
1. By default, the evaluation board is preset at 140mA LED Current by R4. Non-Dimmable by
R6, remove R6 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.
