Features
* including Cycle-by-Cycle current limiting,VDD OVP,VDD clamp and UVLO,Excellent EMI perfoemance is achieved with proprietary frequency shuffling technique. high precision constant voltage and constant current can be achieved by RM326X. Otherwise,RM326X is offered in SOP8 and DIP-8 package. RM326X
Fea
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 externall
