Power management IC for handheld gear — 1.7V to 6V input range
The Texas Instruments TPS65708YZHT is a power management IC designed specifically for handheld and mobile devices. It accepts a wide input voltage from 1.7V up to 6V, covering single-cell Li-ion, multi-cell alkaline, or USB bus power without a separate pre-regulator.
This is a common scenario for legacy handheld/mobile designs that are still in field service or undergoing repair.
16-DSBGA package — layout and assembly considerations
The TPS65708YZHT comes in a 16-DSBGA package measuring 2.24x2.16mm — a 0.5mm-pitch wafer-level chip-scale package. Surface-mount mounting is specified. The DSBGA package has no exposed thermal pad — heat dissipation relies on the PCB copper planes and via array under the package.
