ZXLD1360EV7: 4 ~ 6 LEDs @ 1A, 30V in

Summary

The ZXLD1360EV7, Figure 1, is a single sided evaluation board on aluminium for 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 externally connected LEDs depends on the forward voltage of the LEDs connected. The LED fitted on this evaluation board is the Ostar LEW E2A 4 led device 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 the Vin and Gnd pins.

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