• Manufacturer: DIODES [Diodes Incorporated]

ZXLD1370
Document number: DS32165 Rev. 3 - 2
Applications Information
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.
