The MPX2002 flyback controller incorporates a flyback driver circuit, a synchronous rectifier, safety-compliance isolated feedback, and a high-voltage reference in a single chip. It enables highly efficient power conversion and more reliable, efficient isolation in critical applications such as AC/DC adapters, offline battery chargers, and high-current power supplies.


Multi-Mode PFC and Current Mode LLC Controller With Programmable Audible Noise Reduction Control

The PFC controller employs a patented, digital average current control scheme to achieve hybrid CCM/DCM operation. Under heavy loads, CCM reduces the peak MOSFET current so the controller can be used across a wider load range.
