General Description

TPS54678 device is a full-featured 6-V, 6-A, synchronous step-down current mode converter with two integrated MOSFETs.

TPS54678 enables small designs by integrating the MOSFETs, implementing current mode control to reduce external component count, reducing inductor size by enabling up to 2-MHz switching frequency, and minimizing the IC footprint with a small 3-mm × 3-mm thermally enhanced WQFN package.

TPS54678 provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (VREF) over temperature.

Key Features

  • 1 Two 12-mΩ (typical) MOSFETs for high-efficiency 6-A continuous output current.
  • 200-kHz to 2-MHz Switching frequency.
  • 0.6-V ±1% Voltage reference over temperature (.
  • 40°C to 150°C).
  • Synchronizes to external clock.
  • Start-Up with prebiased voltage.
  • Power good output.
  • Adjustable slow start and sequencing.
  • Cycle-by-cycle current limit and hiccup current protection.
  • Adjustable input voltage UVLO.
  • Thermal.
