With two system management buses (SMBus), Silicon Storage Technology’s SST89C58RC FlashFlex 8-bit microcontroller family supports up to 400 Kbps data throughput in each bus. The 6-mm2 QFN-packaged devices yield operating voltages from 2.7 to 5.5 V and 1 KB on-chip RAM. The microcontrollers
Designed to drive upper and lower power N-Channel MOSFETs in a synchronous converter, the LTC4447 from Linear Technology, can deliver 5A for buck or boost DC/DC converters. This driver, combined with power MOSFETs and one of Linear Technology's DC/DC controllers, forms a complete synchronous regulator that can be used as a step-down or step-up DC/DC converter. The device drives both
In 1839, French physicist Alexandre Edmond Becquerel discovered the “photovoltaic” effect, or the natural phenomenon which allows the conversion of solar into electrical energy. Over the next 150 years, this inexorably led to solar-powered satellites, solar cars, and solar-panel technology for domestic use. Among their many strengths, financial savings (after the initial investment), environmental conservation, and minimal upkeep, solar panels always suffered weaknesses inherent in a technology that relies on a giant ball of ionized gas 150 million kilometers away.
Housed in 1U-high aluminum cases and providing up to 450 W, the WL7 Series of switchmode power supplies from Acopian have a constant voltage/constant current crossover, and both voltage and current can be programmed with 0- to 10-V control voltages.

With soaring energy costs, all sectors are feeling the crunch, including the thermoelectrics industry. But Nextreme Thermal Solutions has a plan to stem the tide. One potential solution is to convert a system’s thermal energy byproduct into a functional resource. Using a grant from the North Carolina Green Business Fund, Nextreme plans to optimize their thin-film growth process with the goal of doubling the power output of a single device from 250mW to 500mW.
Incorporating the recently PHY1040 laser transceiver and limiting amplifier IC and an off-the shelf 8-bit microcontroller with embedded flash, a hardware and software reference design from Phyworks can create Small Form-factor Pluggable 125 Mbps to 1.25 Gbps optical modules with digital configuration and monitoring capability. The system architecture allows users to configure the PHY1040 in software to meet specific optics and network requirements and
A bit of C code that runs on a microprocessor does not create a software-defined radio (SDR). Most SDRs use a traditional signal-sampling technique, followed by much software massaging of data. But semiconductor companies can now put more of the analog signal-handling elements on a chip. This column provides an update on both techniques.
With a footprint 40% smaller than a standard SO-8 and a height of 0.7 mm, a family of 30-V DirectFET MOSFETs enable a smaller footprint and higher power density in synchronous buck converter designs.
