TOPD 7/ 01 3 TOPSwitch- II top221p Family Functional Description TOPSwitch is a self biased and protected linear control current-. TOPSwitch is a top221p self biased and protected linear control cur- rent- to- duty cycle converter with an open drain output. The output voltage ( 5 V) is directly sensed by the Zener diode ( VR1) and the optocoupler ( U2). datasheet search Datasheet search site for Electronic Components , Semiconductors, datasheets, diodes , integrated circuits other semiconductors. The output voltage is determined by the sum of the Zener voltage and the voltage drop across the LED of the optocoupler ( the voltage drop across R1 is negligible). the attached schematic was top221p mentioned as a design example for TOP221P in page six of the datasheet.
Parameters for sensitivity and output timing are. Internal current sense point. 5 PCS POWER TOP221P DIP- 8 Analog IC top221p - Datasheet Reference - EUR 12, 54.
