TIDA-00785 Isolated GaN Driver Reference Design | TI.com

TIDA-00785: This reference design consists of a reinforced dualchannel digital isolator, a GaN gate driver, and isolated power supplies. This compact reference design is intended to control GaN in power supplies, DC-to-DC converters, synchronous rectification, solar inverters, and motor control. An open-loop push-pull topology based power supply for gate drivers provides flexibility in PCB routing. The pushpull transformer driver used in the TIDA-00785 operates at 300 kHz, which helps in reducing the size of the isolation transformer, leading to a compact power supply solution.

PMP20289 400V – 12V/500W High Frequency Resonant Converter Reference Design Using High Voltage GaN Devices | TI.com

PMP20289: The PMP20289 was built and tested to verify the performance of a high frequency (>400kHz nominal switching frequency) LLC series resonant converter (LLC-SRC) implemented with Texas Instrument’s high voltage GaN FETs under nominal (390V to 12V) voltage conversion. The digital controller UCD3138A is used along with the UCD7138 SR controller to optimize LLC-SRC efficiency. TI’s high voltage direct drive GaNFET LMG3410 is used to enable fast switching and be able to minimize dead-time between half-bridge switches. The test results show that 96.8% peak efficiency is achieved at 24A load and 96.3% efficiency is achieved at 42A full load with a switching frequency over 350kHz in a 390V to 12V conversion.
