Texas Instruments Inc. (TI) announced the launch of the industry with integrated FET smallest single-chip 6 A, 17 V synchronous buck converter switch, thus further expanding its use power management integrated circuits based SWIFT (IC) product family. With the current multi-chip converters compared to the size of the high-performance TPS54620 dropped 60%, 6 A, as a complete power solution, the area is less than 195 mm2, equivalent to only a quarter of a postage stamp . 1.6 MHz single-chip DC / DC converter supports 4.5 V ~ 17 V input voltage, which can manage the wireless base station or high-density servers with limited space such as 5 V and 12 V load point of the design process.

TI Power Management Business Unit, Steve Anderson, senior vice president, said: "As the telecommunications designers the density and complexity of the program's continued Tigao, we Xuyaojuyou Ji Cheng, and efficiency higher power management device Lai Zhi Chi 12 V power supply 轨. We continue to develop smaller, more reliable SWIFT converters help designers to quickly develop differentiated products to market. "



In addition to reduction in size than, TPS54620 also has excellent performance and high reliability, such as different temperature accuracy error is + / -1% of the precision voltage reference. Compared with the previous generation of SWIFT device, the converter power conversion efficiency up to 95%, Rds (on) by 25%, can be easily for the deep sub-micron TI digital signal processor (DSP) and FPGA and ASIC, and other embedded processor power supply.

More features and advantages of TPS54620

· SWIFT device supports 6 A continuous, 8 A peak load current and 1.6 V to 17 V input power level.

· 1.6 MHz synchronous converter, which integrates two highly efficient MOSFET (26 milliohms and 19 milliohms), but also used to reduce the maximum size of a small footprint, thermally enhanced 3.5 mm x 3.5 毫米 single-chip QFN package.

* Exchange frequency master clock synchronization to eliminate sensitive data acquisition circuit noise in the beat frequency.

* Feature-rich IC includes power good (PG), opening and tracking pin, can be sorted to meet the demand.

The industry's most extensive single and multi-chip solution

TI offers, including SWIFT and discrete DC / DC converters, including the industry's most extensive step-down converter. In addition to TPS54620 addition, TI also recently introduced a new TPS54418 4A Integrated FET switch, which can support 2.95 V ~ 6 V input voltage range. The device uses a small 3 mm x 3 毫米 QFN package, the switching frequency up to 2 MHz, not only to support synchronization, and power efficiency over 95%. TPS54620 is now in volume production, through TI and its authorized distributors.
