Product Summary

The TPS54910PWP 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 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. The applications of the TPS54910PWP 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.
