TPS54010 (ACTIVE) 3V to 4V Input, 14A Synchronous Step-Down Converter

 

Description

The TPS54010 low-input voltage, high-output current synchronous buck PWM converter in a dc/dc regulator integrating all required active components. Included on the substrate with the listed features are a true, high- performance, voltage error amplifier that enables maximum performance under transient conditions and flexibility in choosing the output filter L and C components; an undervoltage-lockout circuit to prevent start-up until the VIN input voltage reaches 3 V; an internally and externally set slowstart circuit to limit in-rush currents; and a power-good output useful for processor/logic reset, fault signaling, and supply sequencing.

The TPS54010 is available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™ package, which eliminates bulky heat sinks.

Features

  • Separate Low-Voltage Power Bus
  • 8-mΩ MOSFET Switches for High Efficiency at 14-A Continuous Output
  • Adjustable Output Voltage Down to 0.9 V
  • Externally Compensated With 1% Internal
    Reference Accuracy
  • Fast Transient Response
  • Wide PWM Frequency:
    Adjustable 280 kHz to 700 kHz
  • Load Protected by Peak Current Limit and Thermal Shutdown
  • Integrated Solution Reduces Board Area and Total Cost
