AL8807EV2: 1 LED @ 680mA, 6 ~ 30V in

Summary

The AL8807EV2 is an evaluation board showing the application of the Diodes Incorporated AL8807LED driver device on a board suitable for use in an MR16 lamp.

The board has four main connections: two power inputs P1 and P2, and two LED connections Anode(A) and Cathode (K). The evaluation board is preset to drive 680mA into a single LED.

The operating voltage is nominally 12VAC or DC. The 33uH inductor used in the circuit is based onthis nominal supply, which should be connected across the P1 and P2 pins.

Note: The input bridge rectifier provides the board with reverse battery protection.The nominal current, 680mA, is set with the 0R15 sense resistor, R1.

The CTRL pin on the device is not used in this application.
