Microchip Technology Debuts USB/AC Load-Sharing Li-Ion/Li-Polymer Battery Charger
Microchip announces the MCP73871 charge-management controller—a Li-Ion/Li-Polymer charger with an intelligent charge management feature that enables simultaneous AC-DC-adapter or USB-port charging and powering of devices. The single-chip charger features an integrated pass transistor and numerous battery and termination-voltage options, making it ideal for complex, space-constrained portable applications.
DC/DC Converters with 4:1 input deliver 18A/60W regulated 3.3V output in 1.6in. x 2in. package
Murata Power Solutions has introduced its new UEI-series of isolated, wide-range DC/DC Converters that deliver industry leading 50-60W of power output from a standard 40.6 x 50.8 x 10.16mm (1.6in. x 2in. x 0.4in.) PCB mounted, open frame package; plastic cased versions are available upon request.
Synchronous 600mA (ISW) Boost & 400mA (IOUT) Buck Regulator with 2.4MHz Switching Frequency in a 3mm x 3mm QFN
Linear Technology has announced the LTC3523/-2, a combination of a 600mA (ISW) synchronous boost and a 400mA (IOUT) synchronous buck regulator in a 3mm x 3mm QFN-16 package. Both the boost and the buck regulators switch at 2.4MHz in the LTC3523-2 (1.2MHz for the LTC3523), and use current mode, synchronous topologies. The LTC3523/-2 operate from an input voltage range of 1.8V to 5.5V, making them appropriate for single cell Li-Ion/Polymer or dual-...
SL Power Electronics 12W External Power Supply meets EISA Standards
SL Power Electronics has announced a 12W external power supply family that meets both the Environmental Protection Agency’s Energy Star Level IV criteria and the new Energy Independence and Security Act of 2007 (EISA) requirements. The new PW149RB series is compact, measuring 3.35 x 1.81 x 1.30 in (85 x 46 x 33mm). It is available in desktop styles with a single output of 10 to 12W in eight different voltage models.
Power Supply Design Software Suite from Power Integrations
Power Integrations has launched the latest version of its power supply software design tool, PI Expert v7.0. The new software incorporates algorithms to optimize multiple output power supply supplies and to design the primary side clamp circuit and input EMI filtering components. PI Expert v7.0 also includes support for recently released TOPSwitch HX, LinkSwitch II IC families, as well as adding flyback topology support for the DPA Switch range.
PMICs from AnalogicTech extend battery life
By combining two buck converters with a low input voltage used to post-regulate the second buck converter, AnalogicTech’s AAT2782 and AAT2783 are said to extend battery life and reduce board footprint by powering both standard and the lower voltage noise sensitive circuits while maintaining high power efficiency.
A New Solution for Voltage Drops
One of the great difficulties we all face in automation design is the inherent voltage drop along long cables. How do we ensure that when the power gets to the other end its voltage level is enough to actually use? PULS, the leading specialist in DIN Rail power supplies, have used their technical expertise to to provide a solution to this age old problem. After listening to their customers they have developed a new addition to their Dimension ran...
COTS DC/DC converter from XP Power
XP Power has announced the MTC15 and MTC30 dual output additions to its MTC series of fully encapsulated commercial-off-the-shelf (COTS) 4 – 35W DC/DC converters. Suitable for military and avionic platforms with a nominal 28 VDC input, the new 15 W and 30 W units are available with either +/- 12 VDC or +/- 15 VDC outputs.
DC to AC Inverters and Frequency Converters from XP Energy Systems
XP Energy Systems Ltd has added to its industry leading range of industrial power systems designed for use in a variety of high reliability applications.
Programmable power supplies from Lambda
