Uc3842 Ic Circuit Diagram. The output pin of the ic is connected to the gate driver circuit of the power switch which is to be switched. The input voltage for the vcc pin should be 12v to 28v.
The output pin of the ic is connected to the gate driver circuit of the power switch which is to be switched. This ic will operate from a low impedance dc sour ce of 10 v to 30 v. The uc3842 family and highlights the features of each in dividual member the uc3842 uc3843 uc3844 and uc3845 throughout the text the uc3842 part number will be referenced however the generalized circuits and performance characteristics apply to each member of the uc3842 series unless otherwise noted.
A sample application circuit from the uc3842 datasheet is shown below.
A review of cur. How to use uc3842 ic. The input voltage for the vcc pin should be 12v to 28v. Functional description a block diagram of the uc3842 appears in figure 4.
