The NVE021A is a 150-W AC/DC reference design using the company’s GaN power ICs and offers >21 W/in.3 and >95% efficiency. It is more than two times smaller than typical commercial designs and 40% smaller than the previous best-in-class.
The design can be adapted over a power range of 85 to 500 W to enable a new class of converters to address ultra-thin LED TVs, fast-charging laptop adapters, high-density gaming systems, all-in-one PCs, and any other systems seeking high-density or high-efficiency power solutions.
The GaN power ICs enable high-frequency switching to shrink passive components. Soft-switching critical-conduction mode (CrCM) PFC and LLC DC/DC stages operate at working frequencies up to 300 kHz (600 kHz during start-up, burst mode). The reference design is available now for $465 each, which includes a user guide/test report with all schematic and layout design files, plus bill of materials.
