GaN FET Controllers

TI GaN FET controllers are high-performance PWM controllers that work with TI GaN power stages to enable high power density and efficiency compared to traditional silicon MOSFETs. The controllers employ differentiated digital and analog control modes and use I2C and PMBus digital interfaces for simple programming and monitoring for ease of design, adaptive voltage scaling, and enhanced system diagnostics.

Analog controllers

GaN analog controllers enable high-efficiency, power dense DC/DC buck converters and 48V-to-low-voltage POL topologies. They lower total solution cost for processors and ASICs.

Digital controllers

GaN digital controllers save development time with real-time control and connectivity. They support many current sensing technologies across many applications.

Applications

Reliable and integrated GaN controllers work for many applications, including motor drives, enterprise servers and telecommunications.
