  AN-1497 Filterless Class D Amplifiers (Rev. A)
  PDF, 190 Кб, Версия: A, Файл опубликован: 1 май 2013
  As portable electronic devices continue to shrink in size, manufacturers look for ways to push theenvelope and develop the smallest, yet most functional product available. The promise of longer batterylife, smaller size and an enhanced sensory experience appeals to customers. Like the voltage regulatormarket, where system designers moved away from the simple but power hungry linear regulator
