How2Power Today, a monthly newsletter presenting innovative design techniques for power conversion in electronics, has launched a new monthly feature called Powering the Digital Media World. In this column, technology writer Ashok Bindra explores power management challenges confronting designers of communications, computing, and consumer electronics equipment, while describing the new technologies that are being developed to address these challenges.
Ashok’s first column, “Mobile Devices Drive System-Level Approach In Managing Power for Application-Specific Chips” focuses on requirements for functional integration in products such as smart phones, portable navigation devices, and ebooks. As Bindra explains, these mobile electronic devices have complex power management needs because of the numerous electronic functions they contain. These functions include microcontrollers, digital signal processors, audio codecs, audio and RF power amplifiers, radio transceivers, interfaces, and LED drivers.
