Product details

Package and rework considerations

The LM61480Q3RPHRQ1: Housed in a 16-VQFN-HR (4.5 mm × 3.5 mm) package with wettable flank terminals — the exposed flank aids optical inspection and solder-joint reliability under the hot-air station, and the wettable sidewall makes x-ray verification of the QFN easier than a standard VQFN.

Non-synchronous rectifier topology means the low-side switch is an external Schottky diode — the designer picks the diode's forward voltage and thermal rating to match the 8 A load, which gives flexibility in cost vs efficiency but adds a component the synchronous peers skip.
