PMP31375
180VAC to 275VAC input, 96W - 24W AC/DC flyback with self-biasing GaN reference design
PMP31375
概述
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.
特性
- Achieves 92.14% efficiency at 230VAC, 91.91% at 180VAC
- Suitable for high ambient temperature applications: only 25.8ºC delta-T between components and the ambient temperature, while delivering 96W for four seconds and 24W average power
- No load power consumption 46.2mW at 230VAC
- Meets DoE Level VI and CoC V5 Tier2 efficiency standards
