Texas Instruments TPS65036x-Q1 Camera, Radar, & MCU PMICs

Texas Instruments TPS65036x-Q1 Camera, Radar, and MCU PMICs are highly integrated automotive power management ICs for camera, radar, and MCU power systems. The devices combine three step-down converters and one low-dropout regulator, enabling multi-rail power delivery in compact automotive designs.

The TPS65036x-Q1 includes a wide-V_IN BUCK1 converter with input support up to 35V, two low-V_IN step-down converters, and one LDO regulator. The TI TPS65036x-Q1 Camera, Radar, and MCU PMICs support forced fixed-frequency PWM mode or AutoPFM mode across all converters, optional spread-spectrum modulation for EMI reduction, and low-power operation controlled by pin or I²C.

The PMICs are designed for automotive camera modules, radar modules, and safety MCU power applications requiring functional safety support and integrated power sequencing. TPS65036x-Q1 devices are available in a 24-pin VQFN package with wettable flanks and support automotive systems up to ASIL-B hardware integrity.
