Switching frequency is programmable from 100kHz to 2.5MHz, letting the designer trade off inductor size against switching losses — lower frequencies for higher efficiency in tight thermal budgets, higher frequencies for smaller magnetics in space-constrained layouts. ## Output rails and supervisor integration Output 1 delivers 1.1V to 20V at up to 3.2A from the buck converter, sized for a microcontroller core or sensor supply rail. Output 2 delivers 1.1V to 5.5V at 280mA from the LDO, suitable for a CAN transceiver or always-on keep-alive rail. An integrated supervisor monitors the output voltages, eliminating a separate reset IC from the BOM — the part asserts a reset signal if either rail falls outside regulation. No official successor or pin-compatible second source is documented — the TPS65320 base product number covers this single functional variant.","metaTitle":"TPS65320DQPWPRQ1 Automotive Buck+LDO, AEC-Q100, 3.2A","metaDescription":"Texas Instruments TPS65320DQPWPRQ1 automotive power management IC.
