ZXLD1320EV1
REFERENCE DESIGN
The ZXLD1320EV1 is configured to the reference design below. The target application is 1A/1.5A high current
LED driver for single or multiple LEDs with wide input voltage range.
The supply voltage for ZXLD1320EV1 is: VIN=4V ~ 18V.
The ZXLD1320EV1 boards are initially set at LED current of 1A with100mΩ (R3) current sensing resistor. In order
to boost the LED current to 1.5A, on-board 200mΩ (R3A) could made parallel to R3 by means of soldering
jumper pad JP1.
For other reference designs or further applications information please refer to the ZXLD1320 datasheet.
