PowerXR is a switching regulator controller, with three to four outputs. Beyond that it’s an enabling product different than the analog controllers used in the past. Analog controllers have to be designed by the engineer. Once the design is placed on the board, if there is a change, it will require a lot of back-end work. The PowerXR Digital Controllers are similar to digital photography, where the user can take the photo, change it later, and change it again and again, all on the computer, all without touching the film.
