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 35 V. 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 300 mA and operate with an input

voltage range from 3 V to 5.5 V. The TPS65036x-Q1

support Low Power Mode with control from pin or I2C.

The TPS65036x-Q1 is available in a 24-pin VQFN

package (3.5 mm × 3.5 mm).
