18-V PMIC with 3 buck converters and 1 LDO for camera modules up to ASIL B | RGE | 24 | -40 to 125

The TPS650331-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 TPS650331-Q1 is available

in a 24-pin VQFN package (4.00 mm × 4.00 mm).
