Switching frequency and efficiency trade-offs
The TPS63011YFFT: The 2.4 MHz switching frequency keeps the inductor and output capacitors small — typical external components fit in a 4 mm × 4 mm footprint — but the switching losses scale with input voltage, so the datasheet's efficiency curves should be checked against the actual VIN and load current.
Package and board integration — 20-DSBGA
The 20-DSBGA (0.4 mm pitch, 0.25 mm ball diameter) demands a controlled reflow profile with a peak temperature at the solder ball interface, not the package body. X-ray inspection after reflow is recommended to confirm solder-joint integrity under the BGA.
RoHS3 compliant with no exemptions — the part fits EU RoHS and China RoHS BOM requirements without a waiver. Available to order against an RFQ through independent distribution; current pricing and lead time confirmed at quote time.
