The expanding feature sets of next-generation EDGE and 3G multimode mobile devices are driving the demand for DC to DC converters. With the integration of Bluetooth(R), GPS, WLAN and other functionality into mobile devices, the emphasis on current consumption and efficiency has increased proportionally.
Unlike most stand-alone DC to DC converters, RFMD's DC to DC converters combine world-class power amplifier expertise with state-of-the-art, low noise DC to DC converter design to enhance performance and optimize interaction with the Company's front-end solutions. As a result, RFMD's DC to DC converters enable greater functionality in next-generation mobile devices by improving mobile device efficiency and enhancing overall power amplifier performance. RFMD's DC to DC converters can be used in a range of applications and are not restricted to use with RFMD's industry-leading front-end solutions.
Eric Creviston, corporate vice president of RFMD's Cellular Products Group, said, " RFMD continues to develop architectures, circuits and components that improve the efficiency and performance of next-generation mobile communication devices. Our new DC to DC converters are very complementary to the open-loop polar modulation architecture of our POLARIS(TM) EDGE transceivers and are optimized for superior performance with our family of EDGE and WCDMA power amplifiers."
DC to DC converters provide two major customer benefits. First, power amplifier efficiency improvements can be realized at non-optimized output power levels. Power amplifiers are optimized to achieve peak efficiency at maximum output power. Because maximum output power is achieved when handsets are at their greatest distance from cellular base stations, handsets operating near base stations (typical usage) operate at lower output powers and suffer reduced efficiency. This is known as "backed-off" efficiency. A DC to DC converter improves the efficiency of power amplifiers at backed-off output powers, thereby extending battery life and/or talk time.
Second, performance can be optimized over an extended battery voltage discharge profile. Because many circuits are optimized to work at voltages below the battery-supplied voltage, the difference between the battery's voltage and a circuit's optimum supply voltage is dissipated in a voltage regulator, and thus lost in the form of thermal energy. A DC to DC converter provides an efficient method of lowering the battery voltage to a circuit's optimum supply voltage without the loss of thermal energy.
