Texas Instruments Debuts 6-A, 17-V Step-down DC/DC Converter

Texas Instruments, a global semiconductor company, has reportedly unveiled a single-chip, 6-A, 17-V step-down synchronous switcher with integrated FETs called, TPS54620.

 

TPS54620 is a 1.6-MHz monolithic DC/DC converter that facilitates input voltages from 4.5 to 17 V, allowing it to manage space-constrained 5-V and 12-V point-of-load designs, such as a wireless base station or high-density server.

 

According to the company, the new TPS54620 offers a high degree of performance and reliability, such as a highly accurate voltage reference with +/- one percent accuracy over temperature.

 

"As telecommunications designs become more dense and complex, they need more integrated, highly efficient power management devices that support a 12-V power rail," said Steve Anderson, senior vice president of TI's Power Management business unit. "We continue to develop smaller, more robust SWIFT converters, so designers can more quickly develop differentiated products for the market."

 

TPS54620 which is one-fourth the size of a postage stamp, performs at its best with 95-percent power conversion efficiency and a 25 percent lower Rds(on) than previous 6-A SWIFT devices, the converter easily powers deep sub-micron TI digital signal processors (DSPs) and other embedded processors, such as FPGAs and ASICs, says the company.

 

Also, it integrates two high-efficiency MOSFETs (26 milliOhms and 19 milliOhms) and comes in a space-saving, thermally enhanced 3.5 mm x 3.5 mm monolithic QFN package that minimizes footprint and its IC includes power-good, enable and tracking pins for sequencing.

 

The company is currently offering the new TPS54620 through its authorized distributors in a 3.5 mm x 3.5 mm QFN package with suggested resale pricing of $1.95 in 1,000-unit quantities.

 

Texas Instruments (News - Alert) portfolio includes analog, digital signal processing; RF and DLP semiconductor technologies that help customers deliver consumer and industrial electronics.

 

The company’s recent launch includes TPS54418 4-A switcher with integrated FETs, which supports input voltages from 2.95 V to 6 V. The device switches up to 2 MHz, can be synchronized and achieve greater than 95-percent power efficiency in a small 3 mm x 3 mm QFN package.
