3 Description

The TPS65224-Q1 device meets the power

management requirements of the latest processors

and platforms in various safety-relevant applications.

The device is characterized across an ambient

temperature range of -40°C to +125°C, making the

PMIC an excellent choice for various automotive

applications. The device has four step-down DC/DC

(BUCK) converters, of which two can be used in a

dual-phase configuration. Furthermore, the device has

three low drop-out (LDO) regulators, which can also

be used as load-switches.
