Product Summary

The TPS54350PWP is an adaptive on-time D-CAP2 mode synchronous buck converter. The TPS54350PWP enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54350PWP uses the D-CAP2 mode control which provides a fast transient response with no external compensation components. The applications of the TPS54350PWP include Wide Range of Applications for Low Voltage System, Digital TV Power Supply, High Definition Blu-ray Disc Players, Networking Home Terminal, Digital Set Top Box (STB).
