Application Information
The purpose of the ZXGD3104 is to drive a MOSFET as a low-V
Schottky diode replacement in offline power
F
converters. When combined with a low R
MOSFET, it can yield significant power efficiency improvement, whilst
DS(ON)
maintaining design simplicity and incurring minimal component count. Figure 2 shows typical configuration of
ZXGD3104 for synchronous rectification in a 19V output Flyback Adaptor.
