9.1 Application Information

The LMG3624 enables the simple adoption of GaN FET technology in switch-mode power-supply applications. The integrated gate driver, low IN input threshold voltage, and wide AUX input-supply voltage allows the LMG3624 to seamlessly pair with common industry power-supply controllers. The current-sense emulation feature saves power and improves thermal conduction. Using the LMG3624 only requires setting the desired turn-on slew rate with a programming resistor and calculating the current sense resistor.
