Texas Instruments Unveils Industry's Thinnest Power Converter Solution

(Product News, 19 Aug 2008)

Measuring 13x13x0.6mm, Texas Instruments Inc.'s (TI) 6MHz TPS62601 step-down DC/DC converter solution is said to be the industry's smallest and thinnest DC/DC converter for space-constrained applications. The high-efficiency power management IC achieves up to 89 percent power efficiency and only 30µA typical operating quiescent current. The synchronous, switch-mode device's fixed frequency of 6MHz allows the use of only one 0.47µH inductor with a height of 0.6mm and two low-cost ceramic capacitors, without compromising performance and efficiency.

The TPS62601 can deliver DC voltage regulation accuracy of ±1.5 percent. In addition, the device's excellent load transient response, wide input voltage range of 2.3V to 5.5V and 1.8V of output allows it to effectively support single-rail voltage requirements as designers add new features and functionality. The TPS62601 supports many applications, such as memory modules, GPS modules, Bluetooth and Wi-Fi modules or other wireless micro-modules used in ultra-thin smart phones, digital still cameras, portable disk drives and media players.
