SEOUL, KOREA - Texas Instruments (TI) introduced the industry’s first 18-V, 20-A and 30-A synchronous DC/DC buck converters with PMBus interface.

 

The SWIFT TPS544B20 and TPS544C20 converters feature small QFN packages and integrated MOSFETs to drive ASICs in space-constrained and power-dense applications in various markets, including wired and wireless communications, enterprise and cloud computing, and data storage systems. Used in conjunction with TI's award-winning WEBENCH® online design tools, the converters simplify power conversion and speed the power supply design process. For more information, samples and an evaluation module, visitwww.ti.com/tps544b20-pr-kr and www.ti.com/tps544c20-pr-kr.

 

The highly integrated converters feature 0.5 percent reference voltage accuracy and fully differential remote voltage sensing to meet voltage requirements of deep sub-micron processors. Selectable D-CAP or D-CAP2 adaptive on-time control mode is easy to use, provides very fast load transient response and reduces external component count. Programmability, real-time monitoring of the output voltage, current and external temperature, and fault reporting via PMBus simplifies power supply design, increases reliability and reduces component count and system cost. Watch a video on the benefits of buck regulators with PMBus interface.

 

For PMBus applications without output voltage, current and board temperature telemetry, TI offers the 12-A SWIFTTPS53915 buck converter. Get more information on TI’s complete portfolio of SWIFT products.

 

TPS544B20 and TPS544C20 key features and benefits

  • Integrated power MOSFETs support 20-A and 30-A continuous output current.
  • On-chip PMBus interface and non-volatile memory simplify power supply design, provide voltage, current and temperature monitoring, and enable customization of the power supply.
  • Selectable D-CAP or D-CAP2 adaptive on-time control mode eliminates output capacitors and requires no loop compensation, which minimizes the external component count.
  • Other features include internal soft start, input under-voltage protection and thermal shutdown.
