Output 14 V / 1.5 A
IC revisionA

Description

The TPS650330-Q1 device is a highly integrated PMIC for automotive camera modules. This device combinesthree step down converters and one low-dropout (LDO) regulator. The BUCK1 step-down converter has an inputvoltage range up to 18.3 V for connections to power over coax. All converters operate in a forced fixed-frequency PWM mode. The LDO can supply 300 mA and operate with an input voltage range from 2.2 V to 5.5V. The step-down converters and the LDO have separate voltage inputs that enable maximum design andsequencing flexibility.
