It accepts a supply from 3.6 V to 36 V, covering 12 V and 24 V automotive bus transients including cold-crank and load-dump events. The buck output is adjustable from 1.1 V to 20 V; the LDO provides a clean secondary rail from 1.1 V to 5.5 V. Switching frequency is programmable from 100 kHz to 2.5 MHz, allowing trade-offs between inductor size and efficiency. ## AEC-Q100 Grade 1 — 125°C ambient capability For a BOM targeting production vehicles or heavy equipment, this grade is the baseline — not a bonus. ## NRND — last-time-buy planning required Availability and date codes vary; confirm your quantity and required delivery window at quote time. No official pin-compatible successor is listed in the TI documentation, so any replacement will require a board respin. ## 14-HTSSOP thermal pad — layout consideration The 14-HTSSOP package has an exposed thermal pad (PowerPAD) on the underside. The buck converter's 3.2 A output generates significant heat; the PCB copper area beneath the pad sets the junction-to-ambient thermal resistance. A four-layer board with thermal vias to an internal ground plane is standard practice for this part. The 0.65 mm pin pitch is manageable on two-layer boards for the control signals, but the power path demands wider traces.","metaTitle":"TPS65320CQPWPRQ1 Automotive PMIC, Buck+LDO, 3.2A, AEC-Q100","metaDescription":"Texas Instruments TPS65320CQPWPRQ1 dual-output PMIC: 3.2A buck + 280mA LDO, 3.6V-36V input, 125°C, 14-HTSSOP.
