Applications Examples
1.5A Buck LED driver
In this application example, ZXLD1374
is connected as a Buck LED driver with
schematic and parts list shown below.
The LED driver is able to deliver 1.5A of
LED current to single or multiple LEDs
in series with input voltage ranged from
10V to 50V. In order to achieve high
efficiency under high LED current,
Super Barrier Rectifier (SBR) with low
forward
wheeling rectifier.
With only a few extra components, the
ZXLD1374 LED driver is able to deliver
LED power of greater than 60W. This is
suitable for applications which require
high LED power likes high power down
lighting, wall washer, automotive LED
lighting etc.
