PMIC effectively depletes its Atom standby power by 50x

The power management of Freescale Semiconductor Incorporation has cut Intel Corporation’s Atom Z6xx chipset, thus increasing the lifetime of battery not only in smart phones but also in other handset that invariably utilize Atom.

PMIC’s unique discovery

PMIC has been effectively working with Intel for almost two years on chipset for the power management to efficiently reduce the operating power. Moreover, this has lead to 50x reduction in the standby power in relation to the previous generations of Intel’s Atom processors. The power management solution primarily for Atom by Freescale was being integrated win its 130 nm process of mixed signal SmartMOS, in addition to the functions related to the power management. This also avails many interface functions which are needed for any mobile phone, notebook, ereader, iPad like tablet or any other Atom based portable consumer products;
•Battery charging that is intelligent
•Audio codec’s
•24 bit DACs
•10 bit ADCs
•Speaker power amplifiers
•Backlight drivers
•DC/DC converters
•Differential touch screen

Jennings’s characterization as `Made in Heaven’

Mr. Michael Jennings, Freescale’s Product Line Manager mentioned that although Intel avails a design board reference for the Atom Z6xx’s low power version and MP2O support chip that vitally has a socket for daughter board of power management but Freescale’s daughter board was innovated by its 16 years experience in designing chips for power management to meet Intel’s goals for power reduction. This was crucially characterized as made in heaven by Jennings. Though Intel is a processor expert but PMIC is an expert in power management which had earlier successfully worked not only with Motorola but also other handset manufacturers to extend the battery lifetime of other optimum devices. Intel has essentially availed the same reference design and goals to reduce power to integrated products of Maxim and Renesas electronic corporation both of which are competing in Atom power management chipsets.

Freescale, Maxim and Renesas, the trio giants for chipsets

Highest variation offered in the previous version of Intel’s Atom and current offering of ultra low power is that variable parts of processor can be powered to appropriately extend the life of battery. This process is under control of chipsets for power management offered by Freescale, Maxim and Renesas. Although Maxim and Renesas have not yet announced their offerings but Freescale has incredibly claimed that is chipset is an implementation to put the entire function of power management on the unit chip thus leading to the maximum reduction in required board space.

Freescale, the pioneer in chipsets
Freescale’s unique discovery is that by integrating all the functions of power management onto single chip the board area is reduced by 350-500 square millimeters as compared to the other competitors. Freescale’s implementation utilizes two chips and the later one is a small addition to convert voltage from battery into 3.3V that is needed mainly by prime PMIC. With this innovation Freescale claims that thermal management in the design of the handset is simplified and it allows the alternative source of power to be integrating primarily in PMIC. In fine, Freescale is thus producing its powerful PMIC and incredibly have multiple design wins at OEMs and ODMs with the first handsets based on chipset which is due to be hitting the market forcefully at the ulterior this year.
