TPS6590378ZWST General Description

The TPS6590378ZWST is a highly versatile power-management IC that offers a wide range of features for efficient power distribution in various applications. With seven configurable step-down converters, this device can deliver up to 6 A of output current, making it ideal for powering memory, processor cores, I/O components, and more. Additionally, by combining one of these converters with a 3-A regulator, it is possible to achieve up to 9 A of output current, providing flexibility and scalability in power delivery solutions

Key Features
