Fixed 5V boost with 2.4A switch — what it delivers
The Texas Instruments TPS61256CYFFR is a step-up (boost) DC-DC converter that delivers a fixed 5V output from an input ranging from 2.5V to 4.85V. It integrates a 2.4A switch and operates at a 3.5MHz switching frequency, allowing the use of small inductors and ceramics for a compact power stage.
Package and footprint — 9-DSBGA
Housed in a 9-bump DSBGA, the TPS61256CYFFR requires a PCB with fine-line capability and a controlled solder-paste stencil. The 9-DSBGA package is the same footprint used across the TPS61256 family.
