Texas Instruments TPS65224-Q1 Power Management IC (PMIC)

Texas Instruments TPS65224-Q1 Power Management IC (PMIC) meets processor and platform power management requirements in various safety-relevant applications. The TPS65224-Q1 is illustrated across an -40°C to +125°C ambient temperature range, making the PMIC ideal for various automotive applications.

The TI TPS65224-Q1 has four step-down DC/DC (BUCK) converters, two of which can be used in a dual-phase configuration. Likewise, the device has three low drop-out (LDO) regulators, which can also be used as load switches.
