MPN： LMG3422R030RQZT ✓ 啟用中LMG3422R030RQZT 概覽
GaN FETs are a class of wide-bandgap power semiconductors that offer lower gate charge and faster switching than silicon MOSFETs, reducing switching losses and enabling higher power density. The LMG3422R030 integrates the driver and protection circuitry, simplifying design and improving reliability by minimizing parasitic inductance. This integration is part of a broader trend toward power management ICs that combine power stage and control for compact, efficient converters.
Key features include integrated overcurrent and overtemperature protection, a temperature reporting pin, and adjustable gate drive strength. The device supports a wide input voltage range and provides clean switching with minimal ringing, as highlighted in the datasheet. The low-inductance package and integrated driver enable higher switching SOA compared to discrete solutions.
The LMG3422R030 is ideal for applications such as server power supplies, telecom rectifiers, solar inverters, and electric vehicle onboard chargers, where high efficiency and power density are critical. Its 600-V rating and 30-mΩ RDS(on) make it suitable for totem-pole PFC, LLC converters, and other hard-switching topologies.
When designing with this device, ensure proper thermal management via the exposed pad and adequate PCB copper area. The integrated driver simplifies layout, but attention to gate drive loop and snubber design is recommended to minimize ringing. The device is available in tape and reel packaging, with pricing as of 2026-08-27.

主要差異化特點
- Integrated driver reduces component count and parasitic inductance (對比Discrete GaN FET + driver solutions)
- JEDEC JEP180 qualification for hard-switching topologies (對比LMG3422R050)
- Lower RDS(on) than LMG3422R050 (對比LMG3422R050)
設計說明
The LMG3422R030 can dissipate significant power at high currents. Ensure adequate PCB copper area and thermal vias under the exposed pad to keep junction temperature within limits. For 40 A continuous operation, a heatsink or forced airflow may be required.
Minimize the gate drive loop and power loop inductance by placing the device close to the controller and using low-inductance layout techniques. The integrated driver reduces external components, but proper decoupling of VDD and VIN is essential for stable operation.
Do not exceed the absolute maximum ratings for VDS and current. Ensure the PWM input is properly level-shifted and has adequate dead-time to prevent shoot-through. The temperature reporting pin should be monitored for overtemperature conditions.
