This reference design is a power supply delivering 24V, 1A average and up to 96W for 4 seconds. This design supports all cases where high peak power like motor drive or transitory power loads need to be addressed. The integrated quasi-resonant controller, gallium nitride (GaN) switch, and self-biasing section deliver high efficiency while maintaining low stand-by loss and eliminate the need for auxiliary winding in the transformer. Simple transformer structure leads to lower leakage inductance and improves efficiency by reducing snubber loss. Additionally, removing the auxiliary winding and associated components, allows for the reduction of BOM cost and PCB space.
