Application Information

The purpose of the ZXGD3104 is to drive a MOSFET as a low-VF Schottky diode replacement in offline power

converters. When combined with a low RDS(ON) MOSFET, it can yield significant power efficiency improvement, whilst

maintaining design simplicity and incurring minimal component count. Figure 2 shows typical configuration of

ZXGD3104 for synchronous rectification in a 19V output Flyback Adaptor.

Figure 3 shows operating waveforms for ZXGD3104 driving a MOSFET with Qg(TOT) = 124nC in a 19V output Flyback

converter operating in critical conduction mode.
