Semiconductor players like Texas Instruments provide solutions for the LCD/OLED displays to designers, which include the low-power, high-ESD protection touch screen controllers, display interface products, and LCD bias and backlight solutions. They provides the complete power management solution for the Tablet design including a Power Management Unit (PMU) integrated with a USB-OTG Transceiver and a keypad controller. The outstanding efficiency of the power conversion extends battery run time in addition to minimizing heat dissipation. Accurate fuel gauging maximizes usable battery capacity and ensures orderly shutdown. The option to choose between system side and pack side battery fuel gauge offers designers flexibility in design. Similarly, designers using low-power audio codecs that integrate stereo headphone and class-D speaker amplifiers are able to extend battery life. All the above focuses on solving the most critical problem faced by designers i.e. battery life via the analog way!
Conclusion
While the world moves towards higher throughputs and speed with faster processors, the focus of designers to provide simple, efficient and safe products will still have to remain on analog design as the only way to interact with humans is analog!
