3 Description
The LMG2640 is a 650V GaN power-FET half bridge
intended for switch mode power supply applications.
The LMG2640 simplifies design, reduces component
count, and reduces board space by integrating halfbridge
power FETs, gate drivers, bootstrap diode, and
high-side gate-drive level shifter in a 9mm by 7mm
QFN package.
The low-side 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 high-side gate-drive signal level shifter eliminates
noise and burst-mode power dissipation problems
found with external solutions. The smart-switched
GaN bootstrap FET has no diode forward-voltage
drop, avoids overcharging the high-side supply, and
has zero reverse-recovery charge.
The LMG2640 supports converter light-load efficiency
requirements and burst-mode operation with low
quiescent currents and fast start-up times. Protection
features include FET turn-on interlock, under-voltage
lockout (UVLO), cycle-by-cycle current limit, and overtemperature
shut down.
