3 Description

The LMG3612 is a 650-V 120-mΩ GaN power FET

intended for switch-mode power-supply applications.

The LMG3612 simplifies design and reduces

component count by integrating the GaN FET and

gate driver in a 8-mm by 5.3-mm QFN package.

Programmable turn-on slew rates provide EMI and

ringing control.

The LMG3612 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.
