The LMG3526R030 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 LMG3526R030 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 20 V/ns to 150 V/ns, which can be used to actively control EMI and optimize switching performance.
Advanced features include digital temperature reporting, fault detection and zero voltage detection. The temperature of the GaN FET is reported through a variable duty cycle PWM output. Faults reported include overtemperature, overcurrent, and UVLO monitoring. Zero-voltage detection (ZVD) feature can provide a pulse output from ZVD pin when zero-voltage switching is realized.
