Multi-MHz GaN Power Stage Reference Design for High-Speed DC/DC Converters

TIDA-01634

Design files

Overview

This reference design implements a multi-MHz power stage design based on the LMG1210 half-bridge GaN driver and GaN power High Electron Mobility Transistors (HEMTs). With highly efficient switches and flexible dead-time adjustment, this design can significantly improve power density while achieving good efficiency as well as wide control bandwidth. This power stage design can be widely applied to many space-constrained and fast response required applications such as 5G telecom power, servers, and industrial power supplies.

Features
  • Compact GaN-Based Power Stage Design With Switching up to 50 MHz
  • Independent PWM inputs for high side and low side, or single PWM input with adjustable dead time
  • Minimum pulse width of 3 ns
  • High slew rate immunity of 300 V/ns
  • Driver UVLO and overtermpertaure protection

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
