3-kW phase-shifted full bridge with active clamp reference design with > 270-W/in3 power density
This reference design is a GaN-based 3-kW phase-shifted full bridge (PSFB) targeting maximum power density. The design has an active clamp to minimize voltage stress on the secondary synchronous rectifier MOSFETs enabling use of lower voltage-rating MOSFETs with better figure-of-merit (FoM). PMP23126 uses our 30mΩ GaN on the primary side and silicon MOSFETs on the secondary side. The LMG3522 top-side cooled GaN with integrated driver and protection enables higher efficiency by maintaining ZVS over a wider range of operation compared to Si MOSFET. The PSFB operates at 100 kHz and achieves a peak efficiency of 97.74%.

PMP23069 3.6-kW single-phase totem-pole bridgeless PFC reference design with a > 180-W/in³ power density
This reference design is a GaN-based 3.6-kW single-phase continuous conduction mode (CCM) totem-pole power factor correction (PFC) converter targeting maximum power density. The power stage is followed by a small boost converter, which helps to reduce the size of the bulk capacitor. The LMG3522 top-side cooled GaN with integrated driver and protection enables higher efficiency and reduces power supply size and complexity. The F28004x or F28002x C2000™ controller is used for all the advanced controls that includes fast relay control; baby boost operation during AC dropout event; reverse-current-flow protection; and communication between the PFC and the housekeeping controller. The PFC operates at a switching frequency of 65 kHz and achieves peak efficiency of 98.7%.

TIDM-1001 Two Phase Interleaved LLC Resonant Converter Reference Design Using C2000™ MCUs
Resonant converters are popular DC-DC converters frequently used in server, telecom, automotive, industrial, and other power supply applications. Their high performance (efficiency, power density, etc.), improving requirements of the various industry standards, and the ever-increasing power density goals have made these converters a good choice for medium- to high-power applications. This design implements a digitally controlled 500-W two-phase interleaved LLC resonant converter. The system is controlled by a single C2000™ microcontroller (MCU), TMS320F280025C, which also generates PWM waveforms for all power electronic switching devices under all operating modes. This design implements a novel current-sharing technique to accurately achieve current-balancing between phases.
