3 Description

The TPS650350-Q1 device is a highly integrated

power management IC for automotive camera

modules. 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 18.3 V for connections to Power over

Coax (PoC). All converters operate in a forced fixedfrequency

PWM mode. The LDO can supply 300 mA

and operate with an input voltage range from 2.5 V to

5.5 V. The step-down converters and the LDO have

separate voltage inputs that enable maximum design

and sequencing flexibility.

The TPS650350-Q1 is available in a 22-pin WQFN

package (3.0 mm × 3.5 mm).
