Product Summary
The TPS54872PWP 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 3.8 V. The applications of the TPS54872PWP include DDR Memory Termination Voltage, Active Termination of GTL and SSTL High-Speed Logic Families, DAC Controlled High Current Output Stage, Precision Point of Load Power Supply.
