Automotive Infotainment, Cluster and Telematics Require Flexible Voltage Regulators
Automotive infotainment, cluster head unit, and telematics require dedicated front-end voltage regulators that withstand load dump, start-stop, and battery cold crank. The use of dedicated voltage regulators reduces purchasing power due to low volumes, has longer design cycles, and longer time to market. In response to these challenges, a flexible frontend PWM controller configurable as boost or SEPIC or flyback converter has clear advantages of economies of scale and ease of reuse.

Choose a Low IQ, Low Minimum On-Time, and Low EMI Off-Battery PMIC to Power Your Automotive Electronics
Providing power rails for automobile instrument clusters and radio head units presents many conflicting design challenges. These include finding a highly efficient switching regulator with low quiescent current (IQ) that can generate a low output voltage directly from the vehicle battery, while still maintaining low EMI.

Pick a Plug ’n’ Play Linearizer for Your 5G RF Power Amplifier

 

Pick a Plug ’n’ Play Linearizer for Your 5G RF Power Amplifier
In this design solution, we present the features and benefits that 5G telecommunications technology promises to bring and the associated demands that these will place on RF power amplifier (PA) designs. We then review the most commonly used PA linearization techniques, assessing their suitability to meet these demands before presenting a low-power linearizer IC with the potential to greatly simplify the design of PAs used in 5G network applications, while also reducing power consumption.

How to Build a Cooler, Denser ASIC Mining Rig

 

How to Build a Cooler, Denser ASIC Mining Rig
Cryptocurrency and other blockchain technologies are computationally intensive. Current blockchain mining rigs rely on hundreds of dedicated ASICs that consume kilowatts of power for computation. Converters used to power the ASICs must be space- and power-efficient to maximize density and minimize heat generation. After a quick review of this new class of applications, we propose a two-phase buck converter with a coupled inductor as the ideal solution to power the ASICs.
