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.
