DESCRIPTION
As a member of the SWIFT™ family of dc/dc regulators, the TPS54680 low-input voltage high-output current
synchronous buck PWM converter integrates all required active components. Using the TRACKIN pin with other
regulators, simultaneous power up and down are easily implemented. Included on the substrate with the listed
features are a true, high performance, voltage error amplifier that enables maximum performance 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 V; an internally or externally set slow-start circuit to limit inrush currents; and a power good
output useful for processor/logic reset.
The TPS54680 is available in a thermally enhanced 28-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.
