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.
