3 Description
The TPS650330-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 TPS650330-Q1 is available in a 24-pin VQFN
package (4.00 mm × 4.00 mm).
