3 A in a 3x3 mm QFN — automotive buck for tight ECU slots
The 2.5 MHz switching frequency keeps the LC filter small, and the 16-VQFN (3x3 mm) with exposed pad sinks the heat into the board copper.
The 3 V minimum input lets this converter run from a 3.3 V intermediate rail or a battery during cranking; the 17 V maximum covers the nominal 12 V bus with headroom for load-dump transients.
Package and footprint — 16-VQFN with exposed pad
The 16-VFQFN Exposed Pad (3x3 mm) uses the centre pad as the primary thermal path. The 0.50 mm pitch QFN is reworkable with a hot-air station, but the exposed pad makes hand-soldering tricky without a pre-heater. Surface-mount only; no through-hole equivalent.
