ZXLD1362EV3 USER GUIDE DESCRIPTION The ZXLD1362EV3 Figure 1 is a PCB constructed using an aluminium base for evaluating the ZXLD1362 LED driver with internal switch 1 The evaluation board can be used to drive an external choice of LEDs the total forward voltage across the LEDs depending on the number and type connected The operating voltage is nominally higher than 30V for the external LEDs and can be raised to 60V maximum which will reduce the supply current Please refer to the Zetex ZXLD1360 and ZXLD1350 products for applications requiring input voltages lower than 30V The nominal current for the evaluation board is set at 700mA with a 0 15Q sense resistor R1 The 68uH inductor used in the circuit is based on a 30V nominal supply which should be connected ...
