DESCRIPTION

The SWIFT™ family of dc/dc regulators, the

TPS54611, TPS54612, TPS54613, TPS54614,

TPS54615, and TPS54616 low-input voltage

high-output current synchronous-buck PWM

converters integrate all required active components.

Included on the substrate are true, high-performance, voltage error amplifiers that provide high performance

under transient conditions; an under-voltage 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 TPS54611-6 devices are available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™

package, which eliminates bulky heatsinks. Texas

Instruments 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.
