4A peak drive, 20ns rise — what it buys the switching stage
The UCC27324D delivers 4A peak source and 4A peak sink current, enough to slam the gate of a large N-channel or P-channel MOSFET on and off fast. Typical rise time is 20ns, fall time 15ns — that keeps switching losses low in a 100kHz+ converter and gives clean edges for the downstream stage.
Runs from a 4.5V to 15V supply, so it works off a 5V or 12V bias rail without an extra regulator. The logic thresholds are 1V (VIL) and 2V (VIH) — 3.3V logic drives it directly, no level shifter needed.
Supplied in Tube; the base number is UCC27324.
