Example 2: 400mA Boost LED Driver

In this application example, the ZXLD1370 is connected as a boost LED driver. The schematic and parts list are shown below. The LED driver

is able to deliver 400mA of LED current into 12 high-brightness LEDs with an input voltage range of 16V to 32V.

The overall high efficiency of 92%+ makes it ideal for applications such as solar LED street lighting and general LED illuminations.
