SLVS818 – APRIL 2008 3-V TO 6-V INPUT, 3-A OUTPUT, SYNCHRONOUS BUCK PWM SWITCHER WITH INTEGRATED FETs (SWIFT™) 2 • Controlled Baseline • Adjustable Output Voltage Down to 0.9 V With 1% Accuracy – One Assembly Site • Externally Compensated for Design Flexibility – One Test Site • Fast Transient Response – One Fabrication Site • Wide PWM Frequency: Fixed 350 kHz, 550 • Extended Temperature Performance of kHz, or Adjustable 280 kHz to 700 kHz –55 °C to 125°C • Load Protected by Peak Current Limit and • Enhanced Diminishing Manufacturing Sources Thermal Shutdown (DMS) Support • Integrated Solution Reduces Board Area and • Enhanced Product-Change Notification Total Cost • Qualification Pedigree (1) • 60-mΩ MOSFET Switches for High Efficiency at 3-A Continuous Output Source or Sink • Low-Voltage High-Density Systems With Current Power Distributed at 5 V or 3.3 V (1) Component qualification in accordance with JEDEC and • Point of Load Regulation for industry standards to ensure reliable operation over an High-Performance DSPs, FPGAs, ASICs, and extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, Microprocessors temperature cycle, autoclave or unbiased HAST, • Broadband, Networking, and Optical electromigration, bond intermetallic life, and mold compound Communications Infrastructure life. Such qualification testing should not be viewed as justifying use of this component beyond specified • Portable Computing/Notebook PCs performance and environmental limits. As members of the SWIFT™ family of dc/dc regulators, the TPS54310 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 TPS54310 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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 SWIFT, PowerPAD are trademarks of Texas Instruments.
