TI's GaN high-efficiency 1MHz CrM totem-pole PFC converter reference design [Copy link]

High frequency critical conduction mode (CrM) totem pole power factor correction (PFC) is a simple approach to design high density power solutions using GaN.

The TIDA-0961 reference design uses TI's 600V GaN power stage LMG3410 and TI's Piccolo F280049 controller. This high-density (165 x 84 x 40mm) 2-stage dual interleaved 1.6kW design is suitable for a variety of space-constrained applications such as servers, telecom and industrial power applications. Power stage interleaving reduces input and output ripple current. The hardware design meets conducted emissions, surge and EFT requirements to help designers achieve 80+ Titanium specifications.

Compact power stage size 65 x 40 x 40mm, power density greater than 250W/inch3
Efficiency up to 98.7% at 230V AC input and full load
TI LMG3410 GaN power stage with integrated driver and protection features ensures circuit reliability and simplifies design
Fully digitally controlled using TI Piccolo F280049 controller
Eliminates external cooling requirements up to 55°C ambient operation and 50% load
