DESCRIPTION
The SWIFTfamily 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) PowerPADpackage,
which eliminates bulky heatsinks. Texas Instruments
provides evaluation modules and the SWIFTdesigner
software tool to aid in quickly achieving high-performance
power supply designs to meet aggressive equipment
development cycles.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments
semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date. Products
conform to specifications per the terms of Texas Instruments standard warranty.
Production processing does not necessarily include testing of all parameters.
