MM3665

AC-DC Primary Side Controller ICs.
The products integrate the external regulator necessary for the circuit configuration.
Optimal control tailored to the characteristics of each load range is achieved by utilizing Fixed Frequency PWM control during heavy load conditions, and Bottom-Skip Quasi-Resonant control during medium and light load conditions.

Features

Compatible with USB-PD
Less parts
Auto correction of protection condition
Low standby power
