TPS65320C-Q1

Automotive 3.2-A buck converter + 280-mA LDO

Automotive 3.2-A buck converter + 280-mA LDO. For low-voltage automotive rails within its operating input range; the 36V input ceiling does not permit a direct nominal 48V connection. Review preregulation/protection, load and thermals.

LifecycleNRND
In one sentence: TI lists AEC-Q100 Grade 1 over -40 to +125°C; TI also marks the device NRND. Existing designs may continue, but new designs should confirm alternates and supply first. TI's product page does not list a functional-safety category. Treat it as a regular automotive part and perform your own failure-mode analysis for safety functions.

Orderable variants (OPNs)

The GPN is for selection; the full OPN is for ordering. These examples were observed on the verification date, not live stock. Variants may differ in package, temperature, gain/threshold and, for PMICs, NVM/sequencing. Distinguish TA from TJ in the exact datasheet.

FAQ

Is TPS65320C-Q1 automotive qualified?

TI lists AEC-Q100 Grade 1 over -40 to +125°C. Package and temperature can differ by OPN; verify the ordering table and TI datasheet.

Which OPNs are available for TPS65320C-Q1?

TI's product page currently lists 1 OPN; this page shows the first 1 OPN, including TPS65320CQPWPRQ1. Use the full OPN for ordering, not the GPN.

Where can I check price, stock and lead time for TPS65320C-Q1?

NuAxi does not invent stock or pricing on this page. Use TI's ordering page and authorized distributors for live stock, lead time and quotations; verify package, temperature, pinout and software before substitution.

Can TPS65320C-Q1 still be used in new designs?

TI marks it NRND (not recommended for new designs). Existing projects may continue, but new designs should confirm alternates, lifecycle and long-term supply.
