Texas Instruments  TPS54428EVM-052

The TPS54428EVM-052 evaluation module (EVM) is a fully assembled and tested circuit for evaluating the TPS54428 Synchronous Step-Down DC-DC Converter with Eco-Mode. The EVM operates from a 4.5V to 18V input and provides a 1.05V output at up to 4A. The main control loop for the EVM uses D-CAP2 mode control, which provides a very fast transient response with no external components. An integrated Auto-Skip Eco mode function provides higher efficiency at light load.
