TI introduces industry's first 65-V synchronous step-down converter with Fly-Buck™ capability

New converter increases output power, improves power density and simplifies multi-output design for industrial, smart grid, automotive applications

DALLAS, March 5, 2015 — (PRNewswire) —  Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry's first 65-V synchronous step-down converter that provides isolated bias supplies up to 15 W – without the need for an opto-coupler. As part of TI's innovative Fly-Buck power portfolio, the LM5160A improves power density and addresses higher power needs more efficiently and reliably in industrial and automotive applications, such as three-phase AC motor drives, programmable logic controllers (PLCs), smart metering, renewable energy or grid infrastructure, factory automation, power over Ethernet (POE) IP cameras and electric vehicles. For more information, samples and evaluation boards, visit http://www.ti.com/lm5160A-pr. See the LM5160A in TI's booth #1001 at the Applied Power Electronics Conference (APEC), March 16-18, in Charlotte, North Carolina. Follow TI at www.ti.com/APEC15.

TI introduces industry's first 65-V synchronous step-down converter with Fly-Buck(TM) capability

The LM5160A converter features a constant on-time control that requires no loop compensation and supports high step-down ratios with fast transient response. The innovative converter, which supports a wide-input voltage of 4.5 V to 65 V, can generate positive and negative bias-supply rails in non-isolated designs, or single and multiple isolated outputs, while minimizing solution size and simplifying the design compared to traditional flyback solutions. Used in conjunction with award-winning WEBENCH® online design tools, the LM5160A speeds time to market of high-power DC/DC designs.

Key features and benefits of the LM5160A:

  • The 4.5- to 65-V input voltage range allows the converter to efficiently operate in harsh transient conditions without the need for input clamp circuits, resulting in higher reliability.
  • Constant on-time control provides fast transient response and results in lower component count.
  • Programmable soft start reduces in-rush currents when powering up into heavy loads or large capacitance.
  • Internal ±1 percent voltage reference and VOUT error correction improve accuracy across line, load and temperature.

The newest Fly-Buck converter joins TI's proven DC/DC portfolio with industry-leading, high-performance power conversion. TI also offers several devices with its Fly-Buck architecture, including the LM5017 converter, which supports input voltages up to 100 V.
