Application information
The purpose of the ZXGD3103 is to drive a MOSFET as a low-V
F
Schottky diode replacement in offline
power converters. When combined with a low R
DS(ON)
MOSFET, it can yield significant power efficiency
improvement, whilst maintaining design simplicity and incurring minimal component count. Figure 1 and 2
show typical configuration of ZXGD3103 for synchronous rectification in a Flyback and a multiple output
resonant converter.
