It is an AC-DC secondary control IC.
The MM3878 is a secondary side synchronous rectification control IC that supports PWM / QR control, which dynamically changes the off timing according to the power supply status to maximize the effect of synchronous rectification and immediately turns off in the event of an abnormality such as a sudden load change. This prevents backflow.
