DIODES AL1698K 120VAC Dimmable LED Driver
General Description
This demonstration board utilizes the AL1698K Boost LED driver-converter with single winding inductor providing a cost effective triac dimmable solution for offline high brightness LED applications. This user-friendly evaluation board provides users with quick connection to their different types of LED strings. The demonstration board can be modified easily to adjust the LED output current and the number of series connected LEDs that are driven. A BOM, schematic, and layout are included. The layout describes the parts used on this demonstration board, along with measured performance characteristics. These materials can be used as a reference design.

Board Layouts
Quick Start Guide
- 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 LED+ terminal of the evaluation board.
- Connect the cathode wire of the LED string to the LED- terminal of the evaluation board.
- Connect two AC line wires to the AC-L and AC-N terminals on the evaluation board.
- 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.
- Turn on the main switch. LED string should light up with LED.
DO NOT TOUCH THE BOARD, LEDs OR BARE WIRING.
Caution : The AL1698K is a non-isolated design. All terminals carry high voltage during operation!
