Description

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.

Features
  • Compact  power stage of size 65 x 40 x 40 mm with power density of >250W/inch3
  • 98.7% efficiency at full load and 230-V AC input
  • TI’s LMG3410 GaN power stage with an integrated driver and protection ensures circuit reliability and eases design
  • Full digital control using TI’s Piccolo™ F280049 controller
  • Eliminates need for external cooling up to 55°C ambient operation and 50% load
