The webinar series is a corridor event made possible by the financial support of the sponsors with the intention […]
Energy storage by the Farad, Part 3: Hybrid supercapacitors
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. Just as with rechargeable batteries, supercapacitors need proper management to optimize their performance and avoid mishaps. In many ways, the supervisory requirements for both are similar but there are some differences. Vendors of power-management ICs […]
700-V buck regulators billed as EMI friendly
Renesas Electronics Corporation unveiled a family of new 700V buck regulators that offers designers numerous advantages over competitive solutions. The new RAA2230XX devices deliver superior power consumption, noise, and EMI suppression, as well as reduced overall system cost. They are ideal for a wide range of applications, including home appliances, sensing systems such as smoke […]
Energy storage by the Farad, Part 2: Supercapacitors & batteries
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. The previous part of this article established the context for supercapacitors and explained their structure in simplistic terms; obviously, this is a component with deep physics, chemistry, materials-science considerations, and manufacturing issues. The first widely […]
Energy storage by the Farad, Part 1: Supercapacitor basics
Engineers can choose between batteries, supercapacitors, or “best of both” hybrid supercapacitors for operating and backup power and energy storage. Many systems operate from an available line-operated supply or replaceable batteries for power. However, in others, there is a need in many systems to continually capture, store, and then deliver energy to power the system. […]
Class D/G audio power amp features low noise, low quiescent power consumption
Maxim Integrated Products, Inc. unveiled the MAX98396 Class D/G speaker amplifier with the industry’s lowest noise and lowest quiescent power consumption, which is nearly five times lower power than similar amplifiers. The 20V digital input audio power amplifier offers 12.7mW of quiescent power to meet and exceed the industry’s power compliance regulations, which support the always-on […]
High-frequency 100-W PoL converters target USB-PD applications
The CO2 Smart Power family of wide-voltage, high-frequency point-of-load converters now includes a 100-W device targeting USB-PD applications designed to deliver industry-leading efficiency. Operating at a switching speed of 667 kHz, the SZDL3105B fully-integrated dc/dc converter (buck regulator) can supply up to 5 A and 100 W of output power. It accommodates industry-leading wide input […]
GaN is cost-effective in motor drive applications
By Eric Persson, Senior Principal Engineer AC-DC Applications, Infineon Technologies We take motors for granted – they have been with us since Benjamin Franklin experimented with electrostatic types nearly three hundred years ago – but the days are long gone when they were controlled in a simple on/off way. Motors in today’s applications, from clothes […]
GaN power amplifiers deliver high RF output, ensure signals retain characteristics
Satellite communication systems use complex modulation schemes to achieve the blazingly fast data rates required to deliver video and broadband data. To attain this, they must deliver high RF output power while simultaneously ensuring the signals retain their desired characteristics. The new GMICP2731-10 GaN MMIC power amplifier announced by Microchip Technology Inc. helps meet both of these requirements. […]
