The LMG3522R050 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 LMG3522R050 integrates a silicon driver that enables switching speed up to 150 V/ns. TI’s integrated precision gate bias results in higher switching SOA compared to discrete silicon gate drivers. This integration, combined with TI’s 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 15 V/ns to 150 V/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.

開發板

LMG342X-BB-EVM — 適用 LMG342x 系列的 LMG342x GaN 系統級評估主機板

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 EVM 可快速測量 GaN 裝置切換。此 EVM 能夠提供高達 12 A 的輸出電流,運用適當的溫度管理 (強制空氣、低頻率運作等),確保不超過最高運作溫度。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。
