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, 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 TPS54110 device is available in a thermally enhanced
20-pin TSSOP (PWP) PowerPAD package, which
eliminates bulky heatsinks. TI 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.
