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.

Through Marvell’s innovative digital signal processing (DSP) solution, the 88EM8011 controller improves the steady state and transient performance. The combination of the MMC built on top of the DSP solution elevates industry standards for PFC controllers.

The proprietary adaptive over-current protection ability ensures constant power constraint. The safety provisions include open loop and a high voltage protection protocol.

The 8-pin SOIC and DIP packages facilitate application by minimizing the requirements for external components as well as for board space. This guarantees simple system design at a minimum cost making the 88EM8011 the best choice for any PFC application.
