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.
