Introduction
The TPS53015EVM-126 evaluation module (EVM) presents an easy to use reference design for a typical
point-of-load application in a stand-alone module using the TPS53015 controller in cost sensitive
applications.

Description
The TPS53015EVM-126 provides the user with a convenient way to evaluate the TPS53015 D-CAP2™
mode control in a cost sensitive application. Providing a 1.05-V output at up to 8 A from a loosely
regulated 12 V (8 V – 22 V) source, the TPS53015EVM-126 is designed to demonstrate the TPS53015 in
a typical point-of-load application while providing a number of test points to evaluate the performance of
the TPS53015.
