Description
General part information
LMG3624 Series
The LMG3624 is a 650V 170mΩ GaN power FET intended for switch-mode power-supply applications. The LMG3624 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 current-sense emulation reduces power dissipation compared to the traditional current-sense resistor and allows the low-side thermal pad to be connected to the cooling PCB power ground.
The LMG3624 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 open-drain FLT pin.
