As members of the SWIFT™ family of DC - DC regulators,
the TPS54311, TPS54312, TPS54313, TPS54314, TPS54315 and TPS54316 low-input-voltage
high-outputcurrent synchronous-buck PWM converters integrate 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 powergood output useful for processor/logic
reset, fault signaling, and supply sequencing.
The TPS54311, TPS54312, TPS54313, TPS54314, TPS54315 and TPS54316 devices are available
in a thermally enhanced 20-pin HTSSOP (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
