The LMG3526R050 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 LMG3526R050 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 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 15 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 (ZVD). The temperature of the GaN FET is reported through a variable duty cycle PWM output. Faults reported include overtemperature, overcurrent, and UVLO monitoring. ZVD feature can provide a pulse output from ZVD pin when zero-voltage switching (ZVS) is realized.
