TPS65224-Q1中文资料适用于 ADAS 处理器且具有 4 个降压转换器和 3 个 LDO、高达 ASIL-B 等级的 5.5V PMIC数据手册TI规格书

描述 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.
