Texas Instruments TPS56X20 Synchronous Step-Down SWIFT™ Voltage Regulators

Texas Instruments TPS56X20 Synchronous Step-Down SWIFT™ Voltage Regulators

Texas Instruments TPS56X20 Synchronous Step-Down SWIFT™ Voltage Regulators are a synchronous DC-DC converter IC with a voltage scaling control to power up micro-processors (MCUs) requiring core voltage (VCORE) tune-ups. After the initial power-up, the output voltage can be programmed/scaled by VID codes sent over an I2C compatible bus. This step-down (buck) converter employs an adaptive on-time D-CAP2 mode control which provides a very fast transient response with no external components. Unlike traditional voltage/current-mode controls, the D-CAP2 supports seamless transition between PWM mode for higher load and Eco-mode™ for light load. Eco-mode maintains high efficiency in light-load.

    • Enabling IC, Reading-back Power-good
    • Hiccup Mode Protection ON/OFF
  • IC Terminal Features
    • Start-up by Using External Resistors Output Voltage with VFB Pin: 0.6V to 1.87V
    • Adjustable Soft-start, Monotonic Pre-Biased Start-up
    • Power-good
    • I2C Address Programming (2bits)

  • Cycle-by-Cycle Overcurrent Limiting Control
  • Thermal Shutdown (TSD)
  • Undervoltage Lockout (UVLO)
  • TSSOP Package (PWP) with PowerPAD™

Applications
  • Media Processors for Consumer Applications: Digital TVs, Set Top Boxes (STB, DVD/Blu-ray Player, Cable/Satellite Modem)
  • SoC Processors
  • High Density Power Distribution Systems


TPS56C20EVM-614 Evaluation Module

TI TPS56C20EVM-614 evaluation module is a single, synchronous buck converter providing 1.1V at 12A from 4.5V to 17V input. The design of the TPS56C20EVM-614 provides access to all the four devices of the IC family: TPS56520, TPS56720, TPS56920, and TPS56C20. The module comes with a TPS56C20 IC soldered, but the user can replace the TPS56C20 with any of the other three ICs to test their performance.
