AC-DC Converters

Primary

It is an AC-DC primary control IC.
The MM3665 has a built-in external regulator that is necessary for the circuit configuration, and by performing fixed frequency PWM control during heavy loads and bottoms ticket pseudo-resonance control during medium / light loads, it is optimal for the characteristics of each load region. Realizes control.
