White LED Drivers for up to 12 LEDs

Thu, 25 Jan 2007 04:02:25 +0100

Its 2.5V to 10V input voltage range enables the device to operate in applications from single or dual cell Li-Ion powered handheld devices as well as 5V fixed inputs. Its high side current sense enables each string of LEDs to be driven by a single wire. The device acts as a constant current source, delivering the same current to each white LED, regardless of fluctuations in the LED's forward voltage drop...

150V DirectFET MOSFET for isolated DC-DC converters

Thu, 25 Jan 2007 04:02:25 +0100

By reducing board space a single DirectFET MOSFET now can take the place of two or three SO-8 packages. The device’s typical 10V RDS(on) of 29 mOhms makes it suited for high-current synchronous rectifier sockets.

Narrow VDC battery charger controller

Tue, 23 Jan 2007 04:02:25 +0100

The ISL6257 has a type III output voltage control system that allows the regulated output to respond quickly to transient loads with minimal change in output voltage. The device has a fast input current limit response to prevent over-current shutdown of the adapter, and...

100mA automotive linear regulator

Sat, 13 Jan 2007 04:19:56 +0100

The integrated active-low microprocessor reset circuit is triggered when the regulator output drops 10% below the nominal voltage, thus providing an early system warning of an impending power failure. An ENABLE input then turns the regulator off. The uncommitted comparator can monitor the input voltage or detect power-fail conditions...

New Foundation Fieldbus Power Supplies Provide Cost-Effective Solution for Single-Segment Power Requirements; Complements and completes Pepperl+Fuchs' family of power supplies to satisfy any Foundation Fieldbus power need

HVSys High-Voltage and Control System

Wed, 03 Jan 2007 17:46:01 +0100

The system can source up to 1800 V of either polarity and may be configured for any photomultiplier type. Further expansion may be achieved by using additional RS485 cards.

Affordable Eco-friendly Zinc-air Battery Technology Waiting for Takers

Wed, 20 Dec 2006 03:32:53 +0100

Zinc-air technology is a cost effective simple technology, which finds its major application in hearing aid devices. This technology could be utilized for alternative solutions in the automotive sector and the portable electronics sector. The lack of awareness among the customers impedes the growth of this market with few manufacturers in the market.

Let there be Lamps

Wed, 06 Dec 2006 14:11:22 +0100

By the company's measurements, eight hours of charging in full sunlight will keep the lamp lighted for 20 hours. Accessory cables, which sell for $15 to $20, allow the solar panel to recharge other things, like cellphones, iPods and cameras...

Switching Power Supplies have open-frame architecture.

Fri, 01 Dec 2006 16:07:59 +0100

Both series accept universal inputs from 85-265 Vac and are available in 11 models that provide single and dual outputs of 5-48 Vdc. All models feature output adjustment potentiometer and internal input filtering.
