The LMG3425R050 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 LMG3425R050 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.

Advanced power management features include digital temperature reporting, fault detection, and ideal diode mode. 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. Ideal diode mode reduces third-quadrant losses by enabling dead-time control.

评估板

LMG342X-BB-EVM — LMG342x 评估模块

LMG342X-BB-EVM 是易于使用的分线板,可将 LMG3422EVM-043 等各种 LMG342xR0x0 半桥板配置为同步降压转换器。通过提供功率级、辅助电源和逻辑电路,该评估模块 (EVM) 可用于快速测量氮化镓 (GaN) 器件的开关速度。该 EVM 能够在提供充分热管理(强制通风、低频运行等)的同时提供高达 12A 的输出电流,从而确保不超出最大工作温度。该 EVM 不适合用于瞬态测量,因为该板是开环板。

仅需要一个脉宽调制输入,即可在电路板上生成互补的脉宽调制信号和相应的死区时间。提供了探测点,从而可使用具有短接地弹簧的示波器探针测量关键逻辑和功率级波形。
