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.

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.
