Quad Output, Highly Efficient Fly-Buck for Isolated Gate Drivers in Inverters - Reference Design (PMP9486)

PMP9486 is afour 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 microinverters 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 solutionfor using Fly-Back or Push-Pull converters. High efficiency of 88% is acheived at 100mA load on each of the outputs.

Возможности
