Text: . First, an input voltage feed-forward characteristic is achieved; i.e., the control circuit , highlights the features of each individual member, the UC3842, UC3843 , UC3844 and UC3845 Throughout the text , circuit becomes simpler, as illustrated in Figure 3. Capacitor Ci and resistor Ri, in Figure 3a add a low , UVLO circuit insures that VCC is adequate to make the UC3842/3/4/5 fully operational before enabling , circuit operation, VCC is developed from auxiliary winding WAux with D1 and GIN. At start-up, however
