The TPS40057 is a member of the TPS4005x family, also is a high-voltage, wide input,synchronous step-down controller. It offers a variety of user programmable functions and is applied to power modules, networking/telecom as well as industrial/servers .This paper focus on introducing the functions such as operating frequency, soft-start time, voltage feed-forward, high-side current limit, and external loop compensation. A synchronous BUCK Controller is designed based on TPS40057. The result of simulation and experiment show the validity of theoretical analysis and parameters design.
