2.2 Example Based on TPS56C231

TPS56C231 is a small, high-efficiency synchronous buck converter with an adaptive on-time DCAP3 control mode. It operates with supply input voltage from 3.8 V to 17 V and is designed to provide up to 12-A output current. It has competitive features including a very accurate reference voltage, fast load transient response, and no requirement for external compensation, adjustable current limit, and both Eco-mode and FCCM operation modes for selection at light-load condition through the configuration of MODE pin (see TPS56C231 3.8-V to 17-V Input , 12-A Synchronous Step-Down Converter).

TPS56C231 is designed for data center and enterprise computing POLs, wireless infrastructure, IPCS, factory automation, high-end DTV and distributed power systems with typical 5-V and 12-V input. This application note will use TPS56C231 as an example to show how to do bench and simulation load transient correlation for loop response.
