ICEpower Unveils New Website

ICEpower announced the launch of its new website. Designed to redefine the visitors' experience, the revamped site offers all the information about the cutting-edge capabilities of ICEpower's audio technology in the different fields of application. The website also includes information about ICEpower's turnkey solutions using its Class-D amplifier modules and the company's comprehensive information on R&D capabilities. There's even a shop for those who want to order individual modules and solutions.

John Melanson, senior technical fellow at Cirrus Logic, has been granted his 500th US patent, an achievement that places him among the world’s most prolific inventors. The Academy Award-winning engineer’s core contributions are within the field of audio and electronics, particularly the analog and mixed-signal technologies that have helped transform the analog world around us into the digital signals at the heart of today’s most advanced products.

Chord Electronics has announced an all-new ground-up-design analog preamplifier, the Ultima Pre 3. The new design harnesses more than 30 years of the company's amplifier-building expertise and takes advantage of the very latest developments in advanced low-distortion, switched-mode power supplies. According to the British company, coupled with the company’s latest circuit design, the Ultima Pre 3 offers exceptionally low noise and new levels of performance.

GaN Systems, the GaN (gallium nitride) power transistor specialist, announced an updated version of its Class-D audio amplifier evaluation kit, allowing evaluation for high-efficiency audio reference designs. Evolving from the original evaluation kit introduced in 2020, GaN Systems released the GeN2 amplifier and companion switched-mode power supply reference design today, shrinking the size and increasing its capabilities for Class-D audio designs.

In this second article, Brian Lowe (Belleson LLC) continues his search for the Unicorn of "Measuring Voltage Regulator Ripple Rejection," this time focusing on the test fixtures. Testing a voltage regulator with exceptionally good performance requires an even more exceptional signal source and measurement setup to measure sub-microVolt ripple across a wide frequency range. Complementing the final article, Jan Didden, offers an informative sidebar about super regulators. This article was originally published in audioXpress, June 2019.

In this article Brian Lowe shares a fascinating journey in his search for a "Unicorn" that is measuring voltage regulator ripple rejection - or power supply rejection ratio (PSRR). Lowe is the founder and principle engineer at Belleson, LLC, and he has devoted a lot of time to this fascinating "quest." This article was originally published in audioXpress, May 2019.

MaxLinear is known for providing robust, high density power solutions offering a wide input voltage range and excellent thermal performance. But this time, the company reach a new height with the new MxL7213 dual 13A or single 26A power module. This complete switch mode DC/DC power supply includes a wide 4.5V to 18V input voltage range and offers better efficiency and thermal performance than anything on the market.
