Application Examples

Example 1: 2.8A Buck LED Driver

In this application example, the ZXLD1370Q is connected as a buck LED driver. The schematic and parts list are shown below. The LED driver is

able to deliver 2.8A of LED current with an input voltage range of 8V to 24V. In order to achieve high efficiency at high LED current, a Super

Barrier Rectifier (SBR

This LED driver is suitable for applications which require high LED current such as LED projector, automatic LED lighting, etc.
