Maxim introduced the MAX97200, a dual-mode Class H headphone amplifier designed for battery-operated portable devices. This amplifier uses Maxim's proprietary DirectDrive(R) II technology to implement an extremely efficient Class H topology. Nearly 100% more efficient than Class AB amplifiers, the MAX97200 substantially extends audio playback time. Additionally, its glitch-free switching architecture and clickless/popless performance provide end...

Users of music phones and MP3 players can benefit from dramatically extended music playback time enabled by two new 25-mW Class-G, DirectPath stereo headphone amplifiers from Texas Instruments, which adjust their voltage supplies to the audio signal to minimize power dissipation. In a standalone Lithium-Ion battery test between TI’s Class-G technology and a competing ground-referenced Class-AB device, the TPA6140A2 and TPA6141A2 reduced pow...

Avago Technologies has announced the latest addition to its family of low-cost, easy to use, high performance Gallium Arsenide (GaAs) low noise amplifier MMIC products for use in a wide range of wireless mobile communications applications. Avago’s new miniature MGA-21108, which measures 2.5 by 2.5 by 0.55mm in an 8-pin STSLP package, is a fully integrated GaAs LNA for use in the 1.5 to 8 GHz band.

In October 2012, Murata Manufacturing Co Ltd will start mass production of the world's thinnest electric double-layer capacitors (DMF Series) featuring low resistance and the highest levels of power density throughout the industry, a benefit when used as an auxiliary power supply for LED flash units.

Assembled With 6 or 12 High Bright White LEDs with Color Temperature of 5000 K to 7000 K and Luminous Flux up to 1740 lm

The latest addition to IST’s portfolio of world-wide patented LED driver technology is the iDrive® White Knight™, the world’s highest powered 32 channel DALI LED driver, which boasts a super slim 1U 19” rack-mounted chassis. Designed specifically for the demanding professional white light market, the White Knight 32 offers unprecedented step-less dimming capabilities down to

DER-284 is a new design for an LED driver that specifically eliminates the electrolytic capacitor, extending operating life, especially when operated at high temperature.

Power Integrations today announced a reference design kit for a 150 W, 48 V power supply for LED streetlights and other industrial/infrastructure lighting systems. The driver circuit described in RDR-292 is more than 93% efficient at 230 VAC input and above 91% at 110 VAC. The design delivers a system power factor of greater than 0.97, THD of less than 10%, and easily meets EN61000-3-2 C. Designs can be scaled from 75 W to 400 W, using the same p...

As LED lighting continues to grow in popularity, especially in residential lighting applications, designers are looking for efficient dimming solutions – when compared to TRIAC methods – that also fit within existing sockets. Additionally, these solutions need to work reliably in a small space while providing high efficiency. To help designers meet this challenge, Fairchild Semiconductor has developed the FL7701 Smart Non-isolated Buck LED dr...

ON Semiconductor has announced the introduction of the NCP1840, a multi-LED driver with the ability to drive up to eight LEDs independently, using any illumination pattern the user creates. The NCP1840 is ideal for multi-LED status indicators that communicate status and diagnostic conditions to the user, and can help differentiate an end product via LED animation.
