TI unveils industry’s thinnest 500-mA power converter solution
Giving portable designers the ability to add more features and functions on a handheld device, Texas Instruments (TI) has announced today the industry's smallest and thinnest 500-mA, step-down DC/DC converter solution for space-constrained applications. The high-efficiency power management integrated circuit (IC) is the first 6-MHz, 500-mA converter to achieve a 13-mm2 solution size with an ultra-thin 0.6-mm total height.
Leveraging TI's analog manufacturing technology, the new 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.
"Portable system designers continue to desire more features on their devices, which require smaller, efficient DC/DC converters to maintain long battery life and system run-times," said Steve Anderson, senior vice president of Power Management, TI. "The TPS62601 gives portable designers access to the smallest, thinnest 500-mA DC/DC solution, which simplifies design and reduces board space and time-to-market."
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 2.3 V to 5.5 V and 1.8 V 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.
The converter also applies energy-saving techniques to help maximize battery run-time. For example, the converter automatically enters a power save mode during light-load operating conditions via an automatic pulse frequency modulation and pulse width modulation switching feature. In shutdown mode, the device's current consumption is reduced to less than 1 uA.
