Switcher with Integrated FETs ( SWIFTв„ў)
Check for Samples: TPS54110 FEATURES DESCRIPTION As members of the SWIFT family of dc/dc regulators,
the TPS54110 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, highperformance, 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. 1 2 Integrated MOSFET Switches for High
