This reference design provides isolated positive and negative voltage rails for Insulated Gate Bipolar Transistor (IGBT) gate drivers from a 24-V DC input supply. It uses a flyback power supply topology to generate four pairs of 15-V and –5-V outputs suitable for powering six IGBT gate drivers of 1 W each. The integration of a 100-V rated primary-side switch within the LM5180 flyback converter together with the elimination of an auxiliary transformer winding enables a compact solution.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
