UC3843 IC – SMD/DIP SOP-8 PWM Controller 8 Pin IC

UC3843 IC – SMD/DIP SOP-8 PWM Controller 8 Pin IC
Description:

The UC3843 SMD IC is a current Mode PWM Controller, meaning it can be used to provide a constant
current by varying the output voltage to the load. While building Switch mode supplies with feedback
there are two modes of control that is commonly used, one is voltage mode control where the output
voltage will kept constant irrespective of the current (CV mode) and the other is current mode control
where the output current will be constant (C mode) irrespective of the voltage.
