RF Micro Devices Inc. (RFMD) disclosed that they have recently entered the market for DC/DC converter power management components. According to the press release, the new DC/DC converters provide approximately 90 percent efficiency over a wide output voltage range with minimal ripple. These products are designed using a low-cost silicon process and are packaged in a low-cost leadless package, measuring 3-by-3mm.

"Our DC/DC converters facilitate the trend toward feature-rich, multimode 3G handsets by accommodating the higher data rates without the associated increase in current consumption," said Eric Creviston, corporate vice president of cellular products for RFMD. "By reducing PA current consumption by more than 50 percent, our converters help extend the battery life in CDMA and W-CDMA applications, which is a top priority among handset manufacturers and consumers."

The new DC/DC converters work with the company's power amplifiers (PAs) and promise to reduce PA current consumption by greater than 50 percent in CDMA and W-CDMA applications.
