TPS54373PWP

Product Summary

The TPS54373PWP is a low-input voltage high-output current synchronous buck PWM converter integrates allrequired active components. Included on the substratewith the listed features are a true, high performance, voltage error amplifier that enables maximum performance and flexibility in choosing the output filterL and C components; an under-voltage-lockout circuitto prevent start-up until the input voltage reaches 3 V; an internally or externally set slow-start circuit to limitin-rush currents; and a power good output useful for processor/logic reset, fault signaling, and supply sequencing. The applications of the TPS54373PWP include Low-Voltage, High-Density Distributed PowerSystems, Point of Load Regulation for HighPerformance DSPs, FPGAs, ASICs and Microprocessors, Broadband, Networking and Optical Communications Infrastructure, Power PC Series Processors.
