Four-rail PMIC in a 25-bump DSBGA
The Texas Instruments TPS65030YZKT is a power management IC that integrates three charge-pump converters and one linear LDO regulator into a single 25-bump DSBGA package. It generates four independent output rails from a 3V to 5V input supply: 5V at 100 mA from the first charge pump, 1.5V at 200 mA from the second, 3.3V at 22 mA from the third, and the LDO provides a fourth rail (voltage/current not separately specified in the summary). The switching frequency is fixed at 1 MHz. This part is designed for space-constrained portable and battery-powered equipment where multiple low-voltage rails are needed from a single Li-ion or 3.3V/5V bus.

The fourth output from the LDO is available but its voltage/current spec is not broken out in the summary — the designer should verify it from the full datasheet. The 1 MHz switching frequency keeps external capacitor values small, which suits the tight PCB area of a 25-bump BGA layout.
Buyers with a BOM line for this part will need to source through independent distribution on a last-time-buy or surplus basis.
