Description for the TPS54226EVM-539
The TPS54226EVM-539 is a fully assembled and tested circuit for evaluating the TPS54428 synchronous step-down converter. The TPS54226EVM-539 operates from a 4.5-V to 18-V input and provides a 1.05-V output up to 2 A. The main control loop of TPS54226 uses D-CAP2™ mode control, which provides a very fast transient response without the need for external components in phase compensation. This solution also provides flexibility with adjsutable soft start feature and ingrated power good function.
