The buck converter delivers 5.3V at 1.2A, while the three LDOs provide 5V, 3.3V, and 3.3V at 350mA each, making it a complete power tree for an automotive ECU or sensor module that needs a pre-regulated bus plus clean analog rails. ## Input voltage range and 24V system fit The supply range spans 5.6V to 40V, which covers both nominal 12V and 24V automotive systems, including load-dump transients up to 40V. The 2MHz to 3MHz switching frequency keeps the buck inductor small, helping the layout fit tight ECU footprints. ## Integrated supervisor saves a watchdog IC Note that the part does not include a sequencer — power-up sequencing must be handled externally or by the system MCU.","metaTitle":"TPS65300QRHFRQ1 Automotive PMIC, 1 Buck + 3 LDOs, 5.6V-40V","metaDescription":"Texas Instruments TPS65300QRHFRQ1 automotive PMIC with 1 buck converter and 3 LDOs.
