3 Description

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 spreadspectrum

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).
