TI Introduces 3.5-A SWIFT™ Buck Regulators With Tightest Reference Accuracy

DALLAS, Nov. 27, 2012 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced two 3.5-A step-down DC/DC converters with an integrated MOSFET and industry-leading reference accuracy of one percent. The SWIFT™ 60-V TPS54360 and 42-V TPS54340 buck regulators operate over a wide input voltage range and the industry's widest temperature range for high-performance industrial, consumer, computing, communication and automotive applications. Using these new products together with TI's WEBENCH® online design tool can simplify and speed the design process. For more information and samples, visit Watch a video demonstration at

The TPS54360 and TPS54340 join TI's family of Eco-Mode™ SWIFT DC/DC converters that operate over a wide input range with low operating and shutdown quiescent current. The family also includes the 0.5-A, 42-V TPS54040A and 1.5A, 60-V TPS54160A that feature precision enable threshold for adjustable under voltage lockout.

Key features and benefits of the TPS54360 and TPS54340 DC/DC converters
  • Wide input range from 4.5 V to 60 V (TPS54360) or 42 V (TPS54340) offers robust input voltage protection.
  • Current mode control allows simple external compensation and flexible component selection.
  • Integrated 92-mOhm high-side MOSFET provides high efficiency at high currents.
  • Industry-leading one-percent reference accuracy from -40 degrees C to 150 degrees C better regulates output voltages over all operating conditions.
  • Low dropout operating mode approaching 100 percent duty cycle minimizes input to output voltage drop.

Availability, packaging and pricing The TPS54360 and TPS54340 DC/DC converters are available in volume now from TI and its authorized distributors. Offered in an 8-pin SOIC PowerPAD™ package, the TPS54360 is priced at US$2.10 and the TPS54340 is US$1.75 in 1,000-unit quantities. The PowerPAD package lowers the thermal resistance to extend the temperature operation range and improve long-term reliability.
