Reference Designs and Associated Training Videos

PMP41081 1-kW, 12-V HHC LLC reference design using C2000™ real-time microcontroller
This reference design is a 1-kW, 400-V to 12-V half-bridge resonant DC/DC platform used to evaluate the load transient performance of hybrid-hysteretic control (HHC) with a C2000™ microcontroller.

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%.

PMP41017 3kW two-phase interleaved half-bridge LLC reference design with GaN and C2000™ MCU
This reference design is a 3-kW, two-phase, interleaved half-bridge inductor-inductor-capacitor (LLC) using the LMG3422 and C2000™ devices.

Digitally Controlled High Efficiency and High Power Density PFC Circuits - Part 2 (Video)
This presentation will introduce two bridgeless PFC designs using C2000 MCU. TI high voltage GaN is used to implement a 3.3kW interleaved CCM totem-pole PFC and a 1.6kW interleaved TRM totem-pole PFC designs. Detailed design considerations are provided to minimize switching loss, current crossover distortion, input current THD and improve efficiency and PF.

TIDA-010062 1-kW, 80 Plus titanium, GaN CCM totem pole bridgeless PFC and half-bridge LLC reference design
This reference design is a digitally controlled, compact 1-kW AC/DC power supply design for server power supply unit (PSU) and telecom rectifier applications. The highly efficient design supports two main power stages, including a front-end continuous conduction mode (CCM) totem-pole bridgeless power factor correction (PFC) stage. The PFC stage features an LMG341x GaN FET with integrated driver to provide enhanced efficiency across a wide load range and meet 80-plus titanium requirements. The design also supports a half-bridge LLC isolated DC/DC stage to achieve a +12-V DC output at 1-kW. Two control cards use C2000™ Entry-Performance MCUs to control both power stages.

TIDM-1007 Interleaved CCM Totem Pole PFC Reference Design (Video)
This video covers the hardware aspects, the control aspects, and the software design that are required to control a totem-pole PFC using a C2000 microcontroller. The test results achieved on this reference design are also presented as part of this presentation.

Variable-frequency, ZVS, 5-kW, GaN-based, two-phase totem-pole PFC reference design
This reference design is a high-density and high-efficiency 5-kW totem-pole power factor correction (PFC) design. The design uses a two-phase totem-pole PFC operating with variable frequency and zero voltage switching (ZVS). The control uses a new topology and improved triangular current mode (iTCM) to achieve both small size and high efficiency. The design uses a high performance processing core inside a TMS320F280049C microcontroller to maintain efficiency over a wide operating range. The PFC operates with variable frequency between 100 kHz and 800 kHz. A peak system efficiency of 99% was achieved with an open-frame power density of 120 W/in3.
