Description
General part information
LMG3622 Series
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), cycle-by-cycle current limit, and overtemperature protection. Overtemperature protection is reported with the opendrain FLT pin.
