Product Summary

The TPS54910PWPR is a 3V to 4V input, 9A output synchronous buck PWM switcher with integrated FETs. The TPS54910PWPR integrates all required active components. Included on the substrate with the listed features are a true, high performance, voltage error amplifier that enables maximum performance under transient conditions and flexibility in choosing the output filter L and C components; an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 3 V; an internally and externally set slow-start circuit to limit in-rush currents; and a power good output useful for processor/logic reset, fault signaling, and supply sequencing. The applications of the TPS54910PWPR include Low-Voltage, High-Density Systems With Power Distributed at 3.3 V, Point of Load Regulation for High Performance DSPs, FPGAs, ASICs and Microprocessors, Broadband, Networking and Optical Communications Infrastructure, Portable Computing/Notebook PCs.
