Texas Instruments Introduces 60V SWIFT™ DC-DC Converter

November 05, 2008 by Jeff Shepard

Expanding on the company’s integrated SWIFT™ family of dc-dc converters, Texas Instruments Inc. (TI) introduced a new 60V input, 1.5A output step-down switcher with integrated FET that is said to achieve significant energy savings in light-load efficiency. The wide-input converter is said to help saves up to 25% of board space compared to competitive wide-input voltage solutions and eases design in industrial and automotive applications.

The TPS54160 non-synchronous buck’s 3.5 to 60V input voltage range provides designers flexibility in applications with input transients. By leveraging TI’s Eco-mode™ light-load switching technique, the converter is able to achieve a low 116µA operating current and 1.3-uA shutdown current, which is said to result in longer system run-times and a more efficient power system design.

In addition, the converter’s high switching frequency range of 300 kHz to 2.5 MHz reduces the size of the output inductors to save board space. The TPS54160’s frequency fold-back and thermal shutdown features allow the converter to protect itself during an overload condition. The TPS54160 also has an integrated track pin that simplifies various sequencing schemes and a clock pin that reduces noise by synchronizing its switching frequency to an external clock.

TI’s SWIFT dc-dc converters serve a broad range of applications, such as telecom, computing, industrial and consumer point of load applications with input voltage ranges as wide as 60 V and output currents as high as 14A.

The TPS54160 is available in 10-pin MSOP PowerPAD™ packaging. Suggested resale pricing in 1,000-unit quantities is $2.40.
