Overview
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-mode operations are utilized to achieve high performance and high efficiency.
In addition,good load regulation is achieved by the built-in cable drop compensation.
Device operates in PFM in CC mode as well at large load condition and it operates in PWM with frequency reduction at light/medium load.
RM326X offers power on soft start control and protection coverage with auto-recovery features including Cycle-by-Cycle current limiting,VDD OVP,VDD clamp and UVLO,Excellent EMI perfoemance is achieved w...
