Camera power PMIC — what this chip does
The Texas Instruments TPS657051YZHR is a power management IC tailored for camera modules, integrating the voltage rails and sequencing needed to run an image sensor and its supporting optics from a single 3.3V to 6V input.
Package reality — 16-DSBGA layout constraints
The TPS657051YZHR is supplied in a 16-DSBGA package measuring 2.24 x 2.16 mm.
No official replacement part is listed under the TPS657 base number. For a camera module PMIC with the same 3.3V~6V input and DSBGA footprint, the buyer should review the TI power management portfolio for a current-generation equivalent, verifying pin compatibility and sequencing requirements.
