1.6 A in a 2x2 mm WSON — where this regulator fits
The 3 MHz switching frequency lets you use small 1 µH to 2.2 µH inductors and ceramic output capacitors, keeping the total solution footprint tight around the 8-WSON (2x2 mm) package.
3 MHz switching — layout and inductor choice
At 3 MHz the switching edges are fast enough that parasitic inductance in the input loop matters. Keep the input capacitor — a 10 µF ceramic with adequate DC-bias derating — within 2 mm of the VIN and GND pins.
For procurement planning, this means the part is qualified for new designs without a near-term obsolescence risk.
