DESCRIPTION
As members of the SWIFT family of dc/dc regulators, the
TPS54311,
TPS54312,
TPS54313,
TPS54314,
TPS54315, and TPS54316 low-input-voltage high-output
current synchronous-buck PWM converters integrate 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 TPS54311, TPS54312, TPS54313, TPS54314,
TPS54315, and TPS54316 devices are available in a
thermally enhanced 20-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.
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.
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.

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.
