Texas Instruments 65-V SWIFT™ DC/DC converter with Eco-mode™ technology focuses on light-load efficiency

Wide-input, monolithic power management IC eases system design and reduces board space in industrial and automotive systems

Nov 3, 2008

DALLAS (Nov. 3, 2008) - Expanding on the company's popular integrated SWIFT&#8482 family of DC/DC converters, Texas Instruments Incorporated (TI) (NYSE:TXN) introduced today a new 65-V input, 1.5-A output step-down switcher with integrated FET that achieves significant energy savings in light-load efficiency. The wide-input converter helps saves up to 25 percent of board space compared to competitive wide-input voltage solutions and eases design in industrial and automotive applications. See: www.ti.com/tps54160-pr.

The TPS54160 non-synchronous buck's 3.5-V to 65-V input voltage range provides designers flexibility in applications with input transients. By leveraging TI's innovative Eco-mode&#8482 light-load switching technique, the converter is able to achieve a low 116-uA operating current and 1.3-uA shutdown current, resulting 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 65-V and output currents as high as 14 A.

Pricing and availability

The TPS54160 is available today from TI and its authorized distributors in 10-pin MSOP PowerPAD&#8482 packaging. Suggested resale pricing in 1,000-unit quantities is $2.40. Reference designs, evaluation modules and the SwitcherPro&#8482 software tool for the TPS54160 are also available online at www.ti.com/tps54160evm.
