The UCC27322TDGKREP is a single-channel low-side gate driver from Texas Instruments, delivering 9 A peak source and sink current with a typical rise and fall time of 20 ns. That combination — high current plus fast edge rate — means it can charge and discharge the gate capacitance of large N-channel or P-channel MOSFETs in tens of nanoseconds, keeping switching losses low in a hard-switched converter.
Supply range and input logic thresholds
The driver operates from a 4 V to 15 V supply rail, covering the standard 5 V and 12 V gate-drive voltages used in most industrial and telecom power supplies.
It comes in an 8-VSSOP package (3.00 mm width), a small footprint that fits tight layouts but still offers enough pin spacing for the high-current gate-drive return path.
