3 Description
The LMG3622 is a 650-V 120-mΩ GaN power FET
intended for switch-mode power-supply applications.
The LMG3622 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 current-sense emulation reduces
power dissipation compared to the traditional currentsense
resistor and allows the low-side thermal pad to
be connected to the cooling PCB power ground.
The LMG3622 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), cycleby-
cycle current limit, and overtemperature protection.
Overtemperature protection is reported with the opendrain
FLT pin.
