2.5 MHz switching — inductor sizing and EMI
At 2.5 MHz the switching frequency pushes the fundamental and its harmonics well above the AM broadcast band, which simplifies input-filter design.
The 5.5 V maximum covers USB VBUS with margin.
Package and assembly — 25-DSBGA
The 25-DSBGA is a fine-pitch BGA. Stencil design and reflow profile need to match the JEDEC standard for this package class.
It is RoHS3 compliant.
