Product details

Switching at 3 MHz allows the use of small external inductors and capacitors, shrinking the total solution footprint — a key advantage in space-constrained portable or battery-powered designs. The output is adjustable via external resistors, with a range from 0.75 V up to 1.54 V, and the device includes a synchronous rectifier for efficiency above 90% across most of the load range.

Package reality: DSBGA and the reflow floor

This part comes in a 12-bump DSBGA (Wafer-Level Chip Scale Package) with a 0.50 mm pitch.
