Atmel Intros Power/Battery Management AT73C203
Atmel Corp. (San Jose, CA) announced the release of its AT73C203 power management standard product for third-generation (3G) wireless platforms. Manufactured on Atmel's low-cost mainstream CMOS process, the AT73C203 has been developed to provide an integrated solution for portable and hand-held applications based on microprocessors that require "smart" power management functions, such as 3G phones, personal digital assistants, palmtop computers, point-of-sales terminals, 3G modems and others.
The AT73C203 features the complete set of power supplies and interfacing systems that is used in a device based on Intel® XScale™ processors. Three sets of step-down switching converters supply application cores, memories and analog blocks each with up to 1.2A. Output-voltage ranges are 0.87V to 1.2V, 1V to 1.80V and 1.70V to 2.60V, with dynamic adjustment in order to optimize current consumption inside the application core. An additional 520mA step-up/down switching converter with an output-voltage range of 3V to 3.4V supplies RF components and peripherals allowing the system to benefit from low lithium-ion battery voltage, down to 2.8V.
Atmel offers the AT73C203 in a 9mm x 9mm, 100-ball, ultra-thin BGA in order to satisfy portable device manufacturers' minimum space requirements. It is available now mounted on a reference design board or as engineering samples. Suggested resale price is $5.25 per unit in quantities of 1,000.
