18V PMIC with three buck converters and one LDO for camera modules

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 fixed-frequency 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).
