Abstract: uc3842 flyback constant current : Providing Power to the UC3842. OSCILLATOR The UC3842 oscillator is programmed as shown in figure 7a , situations and how to correct them when using the UC3842. SLOPECOMPENSATION PREVENTS INSTABILITIES It is , deadtime varies for the UC3842. This minimum deadtime varies with RT and therefore with frequency, as , FLYBACK Figure 24 shows a 25 W multiple-output off-line flyback regulator controlled with the UC3842. , APPLICATION NOTE UC3842 PROVIDES LOW-COST CURRENT-MODE CONTROL The fundamental challenge of
