TI unveils 500-mA power converter solution

Texas Instruments Incorporated (TI) announced has thinnest 500-mA, step-down DC/DC converter solution for space-constrained applications. The power management integrated circuit (IC) is 6-MHz, 500-mA converter to achieve a 13-mm2 solution size with an ultra-thin 0.6-mm total height. The TPS62601 converter achieves up to 89-percent power efficiency and only 30-uA typical operating quiescent current – all from a 0.9 mm x 1.3 mm chip scale package roughly the size of a flake of pepper. The synchronous, switch-mode device’s fixed frequency of 6 MHz allows the use of only one 0.47-uH inductor with a height of 0.6 mm 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 load transient response, wide input voltage range of 2.3 V to 5.5 V and 1.8 V of output allows it to support single-rail voltage requirements as designers add 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.



The TPS62601 is available in volume from TI and its authorized distributors. The device comes in a highly reliable, six-pin, wafer chip scale (0.9 mm x 1.3 mm) package and has a suggested retail price of $1.45 each in quantities of 1,000 units.
