High Power Synchronous Boost Controller Eliminates Heat Sink with 97% Efficiency
Linear Technology just announced the LTC3787, high power two phase single output synchronous step-up DC/DC controller, which replaces the boost diodes with high efficiency N-channel MOSFETs. This solution eliminates the heat sink normally required in medium to high power boost converters. The LTC3787 can produce a 24V at 10A output from a 12V input at up to 97% efficiency. The LTC3787's 135uA standby quiescent current when configured for Burst M...
TDK-Lambda configurable power supplies drive Back-end Electronics in Giant Radio Astronomy telescope in Chile
Earlier this year astronomers and engineers successfully positioned and linked three antennas used in a pioneering telescope based at high altitude in the Atacama region of northern Chile. When fully-commissioned with 66 antennas, the giant telescope will be used to observe the universe with pin-point accuracy and help astronomers answer important questions about our cosmic origins. Inside these antennas are two electronic equipment racks, each p...

The Digital Imperative: The Rising Wave in Power Factor Correction (PFC) Techniques
With the push toward more efficient energy usage, lower carbon footprints and resource sustainability gaining momentum throughout the world, virtually every aspect of energy generation and consumption is coming under intense scrutiny for improvement. Much of the media buzz has centered upon such “big picture” sweeping changes as smart power grids, wind and solar power, carbon sequestration, etc. However, equally important changes are also tak...
Fairchild’s Fixed Output Step-Down Switching Voltage Regulator Delivers Excellent Transient Response, Low Quiescent Current
In portable devices, especially smartphones, data cards and tablets, designers often need to accommodate more functionality than the PMIC can handle, such as additional I/O rails or processors. These rails and/or processors require power from a standalone device in order to function. Fairchild Semiconductor (NYSE: FCS) developed the FAN5358 , a 2MHz, 500mA, synchronous Buck regulator to meet this design challenge.
150W, Encapsulated, DC/DC Converter suits Railway Environments
The RWY 150 Series rugged, railway quality DC/DC converter utilizes high efficiency power conversion topology to deliver 150W output power. It complies fully with the rigorous standards defined in EN 50155 for electronic equipment used on railway rolling stock and is therefore suitable for a wide range of on-board and trackside applications.
