The series TES-5 dc-dc converters made by PowerGate LLC are housed in tiny 1.3- by 0.81- by 0.40-in. surface-mount packages. The 5-W family comprises 21 models that can handle a wide range of inputs and outputs.

BEAR Power Supplies says its new BPS Series of high-voltage dc-dc converters deliver up to five times greater efficiency and 10 times tighter load regulation than similar competitive products.

At half the size of standard DIN-rail power supplies, the PS5R-SB Slim Line devices from IDEC Corp. give designers a good alternative to larger, more expensive units.

Excelsys’ Xcite is a modular supply with 90% efficiency and an output of up to 1200 W.

Al Gore was a big hit as the keynote speaker today at the Embedded Systems Conference. I took six pages of notes, but I doubt I’ll be able to present it as eloquently or humorously as former Vice President and “recovering politician” Gore did. Hopefully, CMP will post the presentation online. Photos and recording devices weren’t permitted....

A new inductor technology achieves a major improvement in cost and efficiency over existing technology by combining the low dc resistance of a foil-wound inductor with the low ac resistance of a Litz wire-wound inductor, according to West Coast Magnetics. For high-current, high-ripple applications at 10 kHz and above, the new technology typically cuts losses by 25% to 50% compared to conventional wire-wound devices.

A pair of dc-dc converters are specifically designed to drive high-current LEDs at a constant current. The LT3478EFE and LT3478EFE-1 from Linear Technology feature a 2.8- to 36-V input range that is suitable for a wide array of applications, including automotive, industrial, and architectural lighting. In boost mode, the devices can drive six 700-mA LEDs in series from a 12-V input.

A robust device suitable for panel-mount configurations, the Model P270 27-mm rotary potentiometer from BI Technologies’ Electronic Components Div., features a life cycle of up to 1 million rotations.

The SN65MLVD2 and SN65MLVD3 dedicated M-LVDS receivers eliminate the need for a transceiver when converting M-LVDS to LVTTL in backplane applications.

The MAX8840/8841/8842 low-dropout linear regulator allows a total solution size as small as 3.9 mm², including external components. Without the need for a bypass capacitor, the MAX8841 has the smallest overall footprint of the three, making it ideal for core, logic, and memory power-supply applications.

The TR60A Series Power-over-Ethernet power supply from PowerGate LLC delivers 48 Vdc at up to 1.2 A, plus data, through a single Ethernet cable.

What does an instrumentation amplifier do? An instrumentation amplifier (also known as an in amp) measures small signals in the presence of a noisy environment. The noise generally is common-mode noise, so while the signal is differential, an in amp uses its common-mode rejection (CMR) to distinguish the signal of interest from the noise. Signal sources in these applications often have output impedances of several kilohms or more, so in amps have a very high...

Ericsson Power Modules adds three new models to its PKM-E series of dc-dc converters, providing additional output voltage ranges, more current, and more power for designers of telecom and data equipment products.

Linear Technology Corp.'s LTC3541 joins a 2.25-MHz synchronous buck regulator and a 300-mA VLDO in one package to create a versatile, high-efficiency power device.

An IC developed by the Pacific Northwest National Laboratory can sense disruptions in a power grid and respond in a quarter of a second to temporarily shut off appliances in consumers' homes, giving the grid a chance to stabilize and avoid a blackout.

TT electronics' IRC Wire and Film Technologies Div. has certified its HSF Series to meet or exceed GR1089 lightning strike specifications. The series is unspiraled, offering advantages where power is maximized.

Vishay Intertechnology's newest additions to its RoHS-compliant aluminum electrolytic capacitors extend both the capacitance range and voltage range available.

ON Semiconductor's NCP1523 and NCP1523B dc-dc converters are well-suited for power-sensitive applications such as micro hard-disk drives found in multimedia portable devices. The two converters also offer integrated soft-start, cycle-by-cycle current limiting, and thermal shutdown protection.

BI Technologies' SWT series of RoHS-compliant sealed tactile switches includes multiple sizes as well as surface-mount and through-hole configurations. Their versatility suits them for a wide variety of applications, including white goods, medical devices, information appliances, automotive, and entertainment equipment.
