The LMG3624 is a 700V 155mΩ 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 × 5.3mm VQFN
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.
