88EM8011 Digital PFC Controller: 88EM8011 The Marvell® 88EM8011 is a high-performance, low-cost, minimum component count power factor correction (PFC) controller. The device is used for universal PFC front-end boost conversion in systems or in standalone products that have power ranges between 10W and 250W. The 88EM8011 includes Marvell’s patented mixed mode control (MMC) that ensures the lowest total harmonics distortion (THD) in the industry. The average current control mode (CCM) is also available as an option. The device has multiple switching frequency options and its soft start is programmable for a variety of applications. The powerful adaptive driver self-adjusting feature allows for flexible application in a wide range of MOSFET sizes, while reducing the EMI.
