ZXLD1360EV2: 4 ~ 6 LEDs @ 1A, 30V in

The ZXLD1360EV2, Figure 1, is an evaluation board for evaluating the ZXLD1360 1000mA LED driver with internal switch. The evaluation board can be used to drive a 1 amp LED, or an external choice of LEDs. The number of external connected LEDs depends on the forward voltage of the LEDs connected. A 6 way connector is provided, to allow an external 0.1 inch connecter to be inserted. The LED fitted on this evaluation board is the Ostar range produced by Osram.

The operating voltage is nominally 30V for the 6 led Ostar, but can be reduced for the 4 led version. The 33uH inductor used in the circuit is based on this nominal supply, which should be connected across +VIN and GND pins.

Note: The evaluation board does not have reverse battery protection. The nominal current for the evaluation board is set at 1000mA with a 0.1W sense resistor, R1.
