The TPS65036x-Q1 device is a highly integrated power management IC for automotive camera and radar modules and MCU power. This device combines three step-down converters and one low-dropout (LDO) regulator. The BUCK1 step-down converter has an input voltage range up to 35V. All converters can operate in a forced fixed-frequency PWM mode or an AutoPFM mode and support optional spread-spectrum modulation (SSM) for EMI reduction. The LDO can supply 300mA and operate with an input voltage range from 3V to 5.5V. The TPS65036x-Q1 support low power mode with control from pin or I2C.

The TPS65036x-Q1 is available in a 24-pin VQFN package (3.5mm × 3.5mm).

The specific orderable part numbers supported are as follows:
