Product Summary
The TPS54974PWP 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 undervoltage-lockout circuit to prevent start-up until the VIN input voltage reaches 3 V. The applications of the TPS54974PWP include Low-Voltage, High-Density Systems With Power Distributed at 2.5 V, 3.3 V Available, Point-of-Load Regulation for High-Performance DSPs, FPGAs, ASICs, and Microprocessors, Broadband, Networking, and Optical Communications Infrastructure, Portable Computing/Notebook PCs.
