Description

  • PMP9486, Reference Design is a four output Fly-Buck converter for driving isolated driver stages (GND wrt high side sources) in DC/AC section of high frequency commercial or residential inverters (eg. solar micro inverters) using the LM5017 regulator IC. The design accepts an input voltage of 20Vin to 40Vin DC (from single panel in micro-inverters or 12V/24V batteries) and provides isolated outputs of 14.5V, 9V @100mA (referenced to same ground). It features a small size and is an inexpensive and more efficient solution for using Fly-Back or Push-Pull converters. High efficiency of 88% is achieved at 100mA load on each of the outputs
