The PMP9460 reference design is a quad isolated output Fly-Buck power supply designed for IGBT gate driver bias in motor drive or inverter applications. It features the LM5017, 7.5-100V wide Vin, 600mA, Constant On-Time (COT), synchronous buck regulator configured in the Fly-Buck topology. The Fly-Buck converter is a simple, cost effective and compact isolated power solution. The reference board generates two pair of +16V and -9V outputs each with 100mA current capability; they are suitable for biasing the gate drivers of two IGBTs. The supply provides good regulation performance over an input voltage range of 19V to 30V.
