AL9910EV10 User Guide 120VAC Non-Dimmable Evaluation General Description This demonstration board utilizes the AL9910 high voltage PWM LED drivercontroller providing a cost effective solution for offline high brightness LED applications that do not require triac dimming. 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 and the number of series connected LEDs that are driven. A bill of materials is included that describes the parts used on this demonstration board. A schematic and layout have also been included along with measured performance characteristics. These materials can be used as a reference design for your products improving your product’s time to market.

Preset the isolated AC source to 120VAC. Ensure that the AC source is switched OFF or disconnected. Connect the anode wire of the LED string to the LD+ of the evaluation board. Connect the cathode wire of the LED string to the LD - terminal of the evaluation board. 5. Connect two AC line wires to the AC+ and AC- terminals on the evaluation board. 6. Ensure that the area around the board is clear and safe, and preferably that the board and LEDs are enclosed in a transparent safety cover. 7. Turn on the main switch. LED string should light up with LED. DO NOT TOUCH THE BOARD, LEDs OR BARE WIRING. Caution: The AL9910EV10.120 is a non-isolated design. All terminals carry high voltage during operation!
