Product details

For a BOM line already qualified, the NRND status means the window for last-time-buy planning is open; for a new design, a direct replacement should be identified.

Automotive-qualified dual-output PMIC

The TPS65320BQPWPRQ1 is an automotive-grade (AEC-Q100) power management IC integrating a step-down (buck) converter rated for 3.2A output and a linear (LDO) regulator rated for 280mA. The input supply range spans 3.6V to 40V, covering automotive battery voltages from cold-crank to load-dump transients.

Sourcing posture

No stock-holding claim; the NRND status means the supply channel is the secondary market and excess inventory — not the factory line.

Frequently asked questions

Is TPS65320BQPWPRQ1 obsolete or NRND?

It is not yet fully obsolete, but Texas Instruments has flagged it for end-of-life planning. Existing production can continue; new designs should select a replacement.
