Power Sources Unlimited announces the XL160 Series of ultra small, highly efficient ac/dc power supplies which pack 160W of power into a 3” x 5” x 1.25” package. The XL160 Series features a universal 90-264VAC input with active PFC. Nine models provide single or multiple outputs (single output models have a secondary 12VDC/1A output). Two models provide ATX outputs in the same 3” x 5” package, perfect for applications where the end...

Linear Technology has introduced the LTC2492, a 4-channel delta-sigma analog-to-digital converter (ADC) that integrates a temperature sensor and a novel front-end design in a tiny 4mm x 3mm DFN package. The LTC2492's Easy Drive™ design results in zero average differential input current, allowing measurements of high impedance input sources without the need for an internal buffer. This patented sampling scheme simplifies the design of front-end ...

New, versatile, dimming circuitry in the LX1691 direct drive CCFL controller from Solid State Supplies, can accept both analogue and digital control inputs and provides six different dimming modes which control both the lamp current amplitude and duty cycle either simultaneously or separately.

The latest entry into Excelsys Technologies family of ultra-compact, high power density power supplies is the Xlite series. These 600W end user configurable units offer up 8 isolated outputs in a slim-line package of just 1U x 260 x 89mm. The Xlite series extends Excelsys innovative “plug and play” architecture allowing end users to configure an application specific power supply in less than 5 minutes.

PowerPax has launched a range of CEC compliant power supplies. This range of 'Green' switch mode power supplies are available as either plug top or desk top units and have very low standby power to meet the new regulations. This range of California Energy Commission compliant power supplies come with output power ratings including 18, 24, 30, 40, 50, 65 and 90W. Output voltage ratings range from 4.5vdc up to 24Vdc.

Powersolve has made significant additions to its AC/DC power supply offering with the launch of a series of ultra compact units ideally suited for those applications where space is at a premium. According to Powersolve’s Managing Director, Peter Clark, they “have a very small footprint for the level of power available”.

Intersil Corporation has announced the release of the ISL6422B and ISL6423B LNB supply and control voltage regulators. These compact and energy efficient regulators are the industry’s first to use an I2C interface to improve system reliability by reporting diagnostics and protecting a satellite set top box (SSTB) against overvoltage, overcurrent, over temperature and backward current.

Operating from a 6V to 60V input supply and achieving up to 95% efficiency, the ZXLD1362 from Zetex Semiconductors can drive up to 16 high power LEDs with an adjustable output current of up to 1A. Provided in the tiny TSOT23-5 package, this LED driver is the smallest of its kind in its current rating, with a maximum footprint of 2.8mm x 2.9mm and off-board height of 1mm.

Following its appointment as UK distributor for UPS products from AEG Power Systems, ThePowerSupplyShop.Co.UK announce the availability of the Protect 1 true online UPS product range. The Protect 1 series is a double conversion UPS with a low noise, true sine wave output with digital signal control and N+X technology for parallel redundancy operation or increased power levels.

Linear Technology has announced the LTC3542, a high efficiency, 2.25 MHz, synchronous buck regulator that delivers up to 500mA of continuous output current from either a 2mm x 2mm DFN or ThinSOT™ package. Using a constant frequency, current mode architecture, the LTC3542 operates from an input voltage range of 2.5V to 5.5V, making it ideal for single cell Li-Ion/Polymer, or multicell Alkaline/NiCad/NiMH applications. It can generate output volt...
