650-V 170-mΩ GaN FET with integrated driver and protection

The LMG3614 is a 650V 170mΩ GaN power FET intended for switch-mode power-supply applications. The LMG3614 simplifies design and reduces component count by integrating the GaN FET and gate driver in a 8mm by 5.3mm QFN package.

Programmable turn-on slew rates provide EMI and ringing control.

The LMG3614 supports converter light-load efficiency requirements and burst-mode operation with low quiescent currents and fast start-up times. Protection features include under-voltage lockout (UVLO) and overtemperature protection. Overtemperature protection is reported with the open-drain FLT pin.
