STMicroelectronics EVLMG4LPWRBR1 GaN-Based Half-Bridge Power Module

STMicroelectronics EVLMG4LPWRBR1 GaN-Based Half-Bridge Power Module is equipped with MASTERGAN4L, which quickly creates topologies without needing a complete PCB design. Fine-tuned to work in an LLC application, the 30mm x 40mm wide FR-4 PCB module provides low-side resistors set to zero and two external body diodes connected parallel to each half-bridge GaN. The module can also work in active clamp or resonant peak current mode flyback applications simply by properly adjusting the low-side sense resistor and removing the parallel diodes.

Two alternative 6V linear regulators are embedded in the PCB: a simple, low-cost regulator and a more precise temperature-independent one. Due to the external bootstrap diode and capacitor, a proper supply for VCC, PVCC, and Vbo is provided. The module accepts only separate driving signals, and the delay time can be modulated by adjusting a dedicated RC filter.

Features

  • GaN half-bridge daughter board equipped with MASTERGAN4L, suitable for power applications requiring fast wake-up time
  • Embedded independently adjustable dead times for LIN and HIN signals
  • Onboard alternate option for 6V
  • Discrete bootstrap diode and capacitor for high-frequency solutions
  • Adjustable low-side shunt to serve peak current mode control algorithms
  • External parallel body diodes to serve LLC application needs
  • 45°C/W junction-to-ambient thermal resistance (without forced airflow) to evaluate large power topologies
  • 30mm x 40mm wide FR-4 PCB
  • RoHS compliant

Applications

  • LLC/high-end consumer electronics
  • Active clamp or resonant peak current mode flyback
