The LMG342xR050 GaN FET with integrated driver and protection is targeted at switch-mode power converters and enables designers to achieve new levels of power density and efficiency.

The LMG342xR050 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 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 20V/ns to 150V/ns, which can be used to actively control EMI and optimize switching performance. The LMG3426R050 includes the zero-voltage detection (ZVD) feature which provides a pulse output from the ZVD pin when zero-voltage switching is realized.

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 overcurrent, short-circuit, overtemperature, VDD UVLO, and high-impedance RDRV pin.

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。
