TPS54972PWPRG4 Description

TPS54972PWPRG4 9A active bus termination/ DDR memory DC/DC converter is a member of the SWIFT? family of dc/dc regulators. Simultaneous power up and down is easily implemented based on the TRACKIN pin. A true, high-performance, voltage error amplifier is included on the substrate to achieve high maximum performance and flexibility in choosing the output filter L and C components. Start-up can be prevented until the input voltage reaches 3 V based on an under-voltage-lockout circuit. Inrush currents can be limited due to an internally or externally set slow-start circuit.
