General Describtion RM326X is a high performance off-line PWM power switch for low power AC/DC charger and adapter applications,It operates in primary-side sensing and regulation.Consequently,opto-coupler and TL431 could be eliminated, Proprietary constant voltage and constant current control is integrated as shown in the figure below.
In constant current control,the current and output power setting can be adjusted externally by the sense resistor RS at CS pin,In constant voltage control,multi-m
