TI introduces industry's highest current 40-A, 16-Vin converter

SWIFT™ step-down DC/DC converter features true differential remote-voltage sensing

DALLAS, May 31, 2016 — (PRNewswire) —  Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry's first 40-A, 16-VIN synchronous step-down DC/DC converter with true differential remote-voltage sensing. The SWIFT TPS548D22 buck converter features a small PowerStack package and integrated MOSFETs to drive application-specific integrated circuits (ASICs) and digital signal processors (DSPs) in space-constrained applications. When used with TI's WEBENCH® Power Designer tool, the TPS548D22 enables engineers to get their power-dense wired and wireless communications; enterprise and cloud computing; and data-storage systems designs to market faster. For more information, samples and an evaluation module, see www.ti.com/tps548d22-pr.

The DPS548D22 from Texas Instruments is the industry's first 40-A, 16-VIN synchronous step-down DC/DC converter with true differential remote-voltage sensing. The SWIFT buck converter features a small PowerStack(TM) package and integrated MOSFETs to drive application-specific integrated circuits (ASICs) and digital signal processors (DSPs) in space-constrained applications.

The TPS548D22 DC/DC converter employs the D-CAP3 control-mode topology, features 0.5 percent reference-voltage accuracy over temperature, and includes true differential remote-voltage sensing to meet voltage requirements of deep submicron processors. Read the blog post, " Using converters in high-current, point-of-load applications."

TPS548D22 key features and benefits

  • Integrated 2.9/1.2 milli-ohm high-/low-side RDS(ON) power MOSFETs increase power density and system reliability.
  • True differential remote-voltage sensing improves load regulation for overall system accuracy.
  • The easy to use D-CAP3 adaptive on-time control mode provides high accuracy and very fast load-transient response and requires no loop compensation, which simplifies design and minimizes external component count. Read the application note, " Accuracy-Enhanced Ramp-Generation Design for D-CAP3 Modulation," for more information on the value of D-CAP3 control mode.
  • PowerStack quad flat no-lead (QFN) packaging offers very high power density and allows easy heat sinking from the single ground pad on the bottom of the integrated circuit (IC) into the internal printed circuit board ground layers with very few vias.
  • Other features that help ensure predictable and reliable operation include internal soft start, input undervoltage protection and thermal shutdown.

The TPS548D22 is the first in a family of 40-A converters to join TI's high-current DC/DC SWIFT product portfolio.
