    • Description

    As a member of the SWIFT family of dc/dc regulators, the TPS54617 low-input voltage high-output current synchronous buck PWM converter offers the same features as the TPS54610 in a small package and higher switching frequency. 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 input voltage reaches 3 V; an internally and externally set slow-start circuit to limit in-rush currents; and a power good output useful for processor/logic reset, fault signaling, and supply sequencing.

    The TPS54617 is available in a thermally enhanced 34 pin QFN (RUV) PowerPAD package, which eliminates bulky heatsinks.
