Start with the news release Power-management controller for standard MOSFETs from Texas Instruments, which we summarised at the time by saying "Texas Instruments has introduced a power-management controller and driver for standard and logic-level N-channel MOSFETs used for low-voltage, secondary-side synchronous rectification. ". Several months prior to that, we featured the news release QDR and DDR SRAMs for reducing power consumption from Cypress Semiconductor: "Cypress Semiconductor has announced Quad Data Rate (QDR) and Double Data Rate (DDR) SRAMs at 36-Mbit and 18-Mbit densities, for networking use in medical imaging and military signal-processing.".
 
In December 2010, we covered the news from Texas Instruments - take a look at TPS54618 for DSP- and FPGA-based communications which says: "The TPS54618 provides 95-per-cent efficiency and operating current of 2.95-6V for point-of-load designs used in DSP- and FPGA-based communications, test and medical equipment. ".
 
Take a look also at the news release from Semtech, Synchronous buck regulator for POL applications, as well as Mosfet designed for 4.5V switching applications from NXP Semiconductors, and Devices target DC/DC converters in telecom apps from International Rectifier.
