MASTERGAN1

Overview

The EVALMASTERGAN1 is a demonstration board for the MASTERGAN1, a high-power density half-bridge driver featuring two 650 V enhancement-mode GaN HEMTs in a system-level package. It integrates a gate driver with power transistors to enable compact, efficient power supplies. The board supports input voltages from 4.5 V to 6 V and provides a 3.3 V output. Designed for evaluating the MASTERGAN1's performance, it facilitates rapid prototyping for high-frequency switching applications, leveraging the integrated self-bootstrapping diode and robust protection mechanisms like UVLO and interlocking functions.

Feature Summary

• Integrates a half-bridge gate driver with two 650 V enhancement-mode GaN HEMTs in a single system-in-package
• Includes built-in bootstrap diode for easy high-side driver supply without external components
• Features UVLO protection on both low-side and high-side drivers to prevent unsafe operation
• Incorporates an interlocking function to automatically manage dead-time and avoid cross-conduction

Applications

• Switching mode power supplies (SMPS)
• Adapters and chargers
• High voltage PFC DC-AC and DC-DC converters
• Uninterruptible Power Supply (UPS) systems
• Solar energy inverters

Procurement Notes

Verify that the specific order corresponds to the EVALMASTERGAN1 evaluation kit rather than the MASTERGAN1 component itself. Confirm compatibility with your control logic by checking the 4.5 V to 6 V input voltage requirement. Ensure the design environment supports the 9x9 mm QFN package footprint associated with the evaluated device. Review the datasheet for thermal management guidelines during evaluation.

Selection Notes

Select this board specifically for evaluating the MASTERGAN1 platform's integration benefits. It is suitable for designs requiring high power density and simplified layout due to the embedded driver. Consider its use for validating high-frequency switching performance compared to discrete MOSFET solutions. It aids in assessing the reduction in bill of materials and board space achieved through the system-in-package approach.

Part Context

The EVALMASTERGAN1 serves as the primary development tool for the MASTERGAN1, which is part of STMicroelectronics' MasterGaN family. This family represents the first advanced system-in-package integrating a 600 V gate driver with two enhancement-mode GaN HEMTs. The platform aims to replace traditional discrete solutions, offering higher efficiency and significantly smaller form factors for high-voltage power conversion applications.

Replacement Considerations

No direct substitute evaluation boards are documented for this specific model. For updated features such as improved standby power consumption, consider evaluating the EVLMG1LPBRDR1 board designed for the MASTERGAN1L variant.
