3 Description

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.
