RM3261S Datasheet - REACTOR

RM3261S high performance off-line PWM power switch

P Power Supply I Loop compensation for CV stability The voltage feedback from auxiliary winding, connected I to resistor divider from auxiliary winding reflecting output voltage,PWM duty cycle is determined by EA output and current sense signal at PIN 4. I Current sense input O HV MOSFET dr.

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.

RM3261S 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
