TPS54310QPWPRQ1

Product Summary

The TPS54310QPWPRQ1 is a low-input-voltage high-output-current synchronous-buck PWM converter integrates all required active components. Included on the substrate with the listed features are a true, high-performance, voltage error amplifier that provides high performance under transient conditions, an under voltage-lockout circuit to prevent start up until the input voltage reaches 3 V, an internally and externally set slow-start circuit tolimit in-rush currents, and a power good output useful for processor/logic reset, fault signaling, and supplysequencing. The applications of the TPS54310QPWPRQ1 include Point of Load Regulation for High Performance DSPs, FPGAs, ASICs, and Microprocessors, Automotive Systems, Navigation Units, Entertainment Modules, Satellite Radio, Industrial High-Density Systems With Power Distributed at 5 V or 3.3 V.
