Fairchild Semiconductor: A Better Way to Manage Leakage Current Failures in LED Backlights

A standard way to configure the backlight is to use two discrete devices: a 100 V MOSFET in a DPAK package and a 100 V Schottky diode, also in a DPAK package. High leakage current of Schottky diode can be a problem in LED backlight units, especially at higher temperatures. Some customers have experienced leakage failure issue of Schottky diode during mass production. One way to improve the leakage failure is to increase the Schottky diode’s voltage rating from 100 V to 120 V, but leakage current can still be an issue when the system temperature is high.
