Beschreibung

High frequency Critical-Conduction-Mode (CrM) Totem-pole power factor correction (PFC) is a simple approach for designing 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 40 mm) 2-stage interleaved 1.6kW design is ideal for many space constrained applications such as server, telecom, and industrial power supplies. Interleaving of the power stages reduces input and output ripple currents. Hardware is designed to pass conducted emissions, surge, and EFT requirements and helps designers achieve 80+ Titanium specifications
