描述
The RTKA271084DE0000BU evaluates the performance of the RAA271084 automotive PMIC, which features a high-voltage primary buck/boost controller, a low-voltage synchronous buck controller, and five low-dropout linear regulators (LDOs), two of which can be used as trackers. The evaluation board is intended for providing MCU power in automotive applications. In addition to four output voltages, the board also includes an SPI interface.
