1 Description
The TPS53819AEVM-123 is designed to use a regulated 12-V bus to produce a regulated 1.2-V output at up
to 25 A of load current. The TPS53819AEVM-123 is designed to demonstrate the TPS53819A in a typical low
voltage application while providing a number of test points to evaluate the performance of the TPS53819A.
1.1 Typical Applications
• Point of load systems
• Storage computer
• Server computer
• Multi-function printer
• Embedded computing
1.2 Features
• Regulated 1.2-V output, marginable and trimmable through the PMBus interface
