Description for the TPS54427EVM-052
The TPS54427EVM-052 is a fully assembled and tested circuit for evaluating the TPS54427 synchronous step-down converter. The EVM operates from a 4.5-V to 18-V input and provides a 1.05-V output up to 4 A. The main control loop of TPS54427 uses D-CAP2™ mode control, which provides a very fast transient response without the need for external components in phase compensation.
