Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

DESCRIPTION/ORDERING INFORMATION
As A member 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 converter integrates 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.
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.
