The TPS6213013AQRGTRQ1 is a Texas Instruments automotive-grade step-down converter from the DCS-Control™ family, qualified to AEC-Q100 and rated for a 125°C junction temperature. It delivers 3 A from a 3 V to 17 V input rail, switching at 2.5 MHz. The fixed 1.3 V output targets modern 1.2 V / 1.35 V core and I/O supplies in automotive ECUs, ADAS modules, and body controllers. The 2.5 MHz switching frequency keeps the inductor small — typically a 1 µH to 2.2 µH shielded type — which saves board area in a space-constrained 16-VQFN layout. Synchronous rectification is integrated, so no external Schottky catch diode is needed. The positive output configuration and fixed-voltage regulation simplify the feedback network to a single output capacitor and inductor — the compensation is internal.
