High-side current-sense amps feature 12 µV maximum offset error
With the proliferation of automation and connectivity throughout the automotive and industrial markets, the need to accurately measure a dynamic current in the presence of high-frequency noise often plagues modern vehicle and factory applications. In order to combat electrically noisy environments and address the need for higher accuracy current measurement, Microchip Technology Inc. introduced its high-side current […]
Reference design lets secondary MCU control primary power
In modern offline AC-DC power solutions, programmability and adaptive control offer the flexibility and intelligence needed by smart home devices to better interface with their power systems. In these systems, a secondary side microcontroller (MCU) is typically not capable of starting a system without the use of a separate bias power supply. A new reference […]
Rad-hard motor controller IC incorporates position sensing for satellites
The need to reduce size, weight, and power on satellites and other space systems continue to challenge the aerospace market. Combining more than 20 commonly used functions into a single chip, Microchip Technology Inc. announced the LX7720 radiation-hardened mixed-signal motor controller, the latest addition to its Space System Manager (SSM) product family. As the industry’s first highly […]

Microchip Technology Inc. announced its expanded portfolio of smaller, lighter […]
PoE chipset delivers 90 W over Ethernet cable
As the industry adopts the latest generation of PoE technology for managing data and power over a single Ethernet cable, users face the challenge of making pre-standard powered devices (PDs) work alongside new IEEE 802.3bt-2018-compliant PDs in an existing Ethernet infrastructure. Many proprietary solutions were brought to market through 2018 that support specifications such as […]
Dual-core digital signal controller
System developers designing high-end embedded control applications can benefit from a new Digital Signal Controller (DSC) with two dsPIC DSC cores in a single chip, now available from Microchip Technology Inc. The dsPIC33CH has one core that is designed to function as a master while the other is designed as a slave. The slave core is useful for […]
Gallery: Cool tech demos at APEC2018, IEEE’s Applied Power Electronics Conference and Exposition
APEC is considered the premier forum for power electronics developments in the U.S. Recently concluded in San Antonio, Tex., the conference and exposition focused on the practical and applied aspects of the power electronics business. In the pages that follow are a few interesting displays that could be found on the exposition floor. NEXT PAGE: […]
What’s all this stuff about capacitive power supplies for LEDs?
A while back a viewer of our 60-W LED bulb teardowns posted a comment about the complexity of the power supplies found in the bases of these bulbs. We talked about some of the reasons these bulbs contain switching supplies in a previous article. But our latest post elicited this comment from another reader: Well, […]
