battery life on smartphones LTE

BARCELONA, Spain, February 28, 2012 / PRNewswire / - Mobile World Congress - Texas Instruments Incorporated (TI) (NASDAQ: TXN) added a new duo of RF DC / DC converters of its portfolio of first plan industry in integrated RF power circuits (ICs). The new national regulators LM3242 and LM3243 are adaptable offers integrated power circuit to minimize power consumption RF amplifier (PA) in all operating conditions. In collaboration with the National LM3241, integrated circuits for longer battery life and reduce the heat dissipated in the battery running 2G, 3G and 4G Term Evolution LTE (Long) mobile devices like smart phones and tablets.

operation of radio circuits in portable devices accounts for a significant amount of total energy consumption - 30 percent or more easily. RF PAs are among the least effective components in the current mobile systems, usually driven at full power regardless of the power actually required. New IT and LM3242 LM3243 dynamically adjust the power supplied to the Palestinian Authority on the basis of the amount of energy is really needed, thus saving a significant amount of energy.
• LM3242 and LM3243
• are unique to the traditional DC / DC switching because they are designed to meet the stringent performance requirements of RF and allow dynamic optimization of the output power PA, savings to a current 50 percent or more of battery consumption and reduce heat to 30 ° C. The two PA ICs with an efficiency of 95 percent and have multiple operating modes to maximize efficiency for all of the battery and the output conditions. The LM3242 is compatible with 3G and 4G applications and has a very small 9 mm

size square solution. The LM3243 comprises a single support and which are active analog bypass mode, allowing the application support 2G, 3G and 4G while keeping the exit control and the minimum size of a solution.

IT features the new RF DC / DC switching converters on stand 8A84 (Hall 8) at Mobile World Congress (MWC) in Barcelona, ??February 1-March 27. For more information, visit www.ti.com/mwc2012.

Key Features and Benefits of the LM3242 and LM3243 RF converters DC / DC switching

variable, the output voltage dynamically adjustable saves energy and reduces heat generation.

intelligent automatic transition between modes of operation optimizes efficiency under all load and battery.

LM3242 supports a maximum of 1-A and is compatible with both 3G and 4G applications. LM3243 supports up to 2.5 A and is compatible with 2G, 3G and 4G applications.
