Product details

12-output PMIC for mobile PC power trees

The TPS650945A0RSKT is a Texas Instruments power management IC integrating 12 switching regulator outputs in a single 64-VQFN (8x8) package. It accepts a 5.6V to 21V input — covering single-cell Li-ion through 2S and 3S battery stacks — and delivers multiple regulated rails for controller/converter applications in mobile PCs. With 12 outputs, this PMIC replaces a bank of discrete buck/boost converters and LDOs, shrinking the power-stage footprint and simplifying the BOM for a mobile PC mainboard.

Input range and temperature grade

The 5.6V–21V input window is wide enough to handle a single-cell Li-ion (3.0V–4.2V boosted to 5.6V) through a 3S stack (9.0V–12.6V) without a pre-regulator.

ROHS3 compliant. Sourced per RFQ against BOM quantity — no stock-holding claim.

Frequently asked questions

What is the closest functional alternative to TPS650945A0RSKT?

The TPS51100DGQ is a single-output DDR converter with a 4.75V input range — it does not match the 12-output, 5.6V–21V capability of the TPS650945A0RSKT. The TPS53317RGBR is a single-output D-CAP+ converter. Neither is a direct second-source; the TPS650945A0RSKT is the only 12-output PMIC in this family for mobile PC applications.
