Applications Information
Example 3:
700mA Buck-Boost LED driver
In this application example, the ZXLD1370 is connected as a buck-boost LED driver. The schematic and parts list are
shown below. The LED driver is able to deliver 700mA of LED current into 4 high-brightness LEDs with an input voltage
range of 7V to 20V.
Since the Buck-boost LED driver handles an input voltage range from below and above the total LED voltage, the versatile
input voltage range make it ideal for automotive lighting applications.
