Page 2: Introduction
1 Introduction The TPS650320-Q1 device is a highly-integrated PMIC 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. All converters operate in a forced fixed- frequency PWM mode.
Page 3: Operation Instructions
GPIO 2.4 Regulator Input Supplies and Features The four regulators on the TPS650320-Q1 EVM can be supplied with multiple supplies. The following tables show the possible supply configurations in addition to key specifications and programmable features for each regulator.
