performance and environmental limits.
As members of the SWIFT family of dc/dc regulators, the TPS54310 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 provides high performance under
transient conditions; 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 TPS54310 device is available in a thermally enhanced 20-pin TSSOP (PWP) PowerPAD package, which
eliminates bulky heatsinks. TI provides evaluation modules and the SWIFT designer software tool to aid in
quickly achieving high-performance power supply designs to meet aggressive equipment development cycles.
