TPS54611-Q1

     The SWIFT family of dc/dc regulators, the TPS54611,TPS54612, TPS54613, TPS54614, TPS54615, and TPS54616 low-input voltage high-output current synchronous-buck PWM converters integrate all required active components. Included on the substrate are true, high-performance, voltage error amplifiers that provide high performance under transient conditions; an under-voltage-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 TPS54611,TPS54612, TPS54613, TPS54614, TPS54615, and TPS54616 devices are available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD package, which eliminates bulky heatsinks. Texas Instruments 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.
      The features of TPS54611,TPS54612, TPS54613, TPS54614, TPS54615, and TPS54616 are Qualification in Accordance With AEC-Q100(1), Qualified for Automotive Applications, Customer-Specific Configuration Control Can, Be Supported Along With Major-Change, Approval 30-mΩ, 12-A Peak MOSFET Switches for High, Efficiency at 6-A Continuous Output Source and Sink, 0.9-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V Fixed, Output Voltage Devices With 1% Initial Accuracy, Internally Compensated for Easy Use and Minimal Component Count, Fast Transient Response Wide PWM Frequency − Fixed 350 kHz, 550 kHz or Adjustable 280 kHz to 700 kHz, Load Protected by Peak Current Limit and Thermal Shutdown, Integrated Solution Reduces Board Area and Total Cost.
