The LMG3522R030-Q1 GaN FET with integrated driver and protections is targeting switch-mode power converters and enables designers to achieve new levels of power density and efficiency.
The LMG3522R030-Q1 integrates a silicon driver that enables switching speed up to 150V/ns. TI’s integrated precision gate bias results in higher switching SOA compared to discrete silicon gate drivers. This integration, combined with TIs low-inductance package, delivers clean switching and minimal ringing in hard-switching power supply topologies. Adjustable gate drive strength allows control of the slew rate from 20V/ns to 150V/ns, which can be used to actively control EMI and optimize switching performance.
Advanced power management features include digital temperature reporting and fault detection. The temperature of the GaN FET is reported through a variable duty cycle PWM output, which simplifies managing device loading. Faults reported include overtemperature, overcurrent, and UVLO monitoring.

LMG342X-BB-EVM — LMG342x 評估模組
LMG342X-BB-EVM 是一款易於使用的分接板,可當作同步降壓轉換器配置任何 LMG342xR0x0 半橋電路板,例如 LMG3422EVM-043。透過提供功率級、偏壓電源和邏輯電路,此評估模組 (EVM) 可快速測量氮化鎵 (GaN) 裝置切換。此 EVM 能夠提供高達 12A 的輸出電流,運用適當的溫度管理 (強制空氣、低頻運作等),確保不超過最高操作溫度。EVM 屬於開迴路電路板,不適合執行瞬態量測。
只需要單脈衝寬度調變輸入,具有互補脈衝寬度調變訊號,和板上產生的對應失效時間。使用具有短接地彈簧的示波器探針,提供探針點來測量主要邏輯和功率級波形。
