3 MHz buck for tight spaces
Output voltage and temperature grade
Output is adjustable (programmable) from a minimum of 0.9 V up to 1.69 V, with fixed presets at 1.1 V and 1.5 V — common core rails for low-power MCUs and RF chips.
The TPS62351YZGR is listed as obsolete. For a BOM line that still calls this exact code, the available stock is what exists in independent distribution and surplus channels. No official replacement is recorded in the lifecycle entry, so a pin-compatible drop-in is not guaranteed — expect to qualify an alternative if you are designing a new board.
Package and procurement note
Supplied in a 12-bump DSBGA package — wafer-level chip-scale. The small footprint demands careful PCB layout and a controlled reflow profile; the solder joints are under the die, so post-assembly inspection requires X-ray.
