Hello everyone! I hope you all will be absolutely fine and having fun. I am going to give you the detailed discussion about Introduction to UC3843 today. UC 843 is basically a current mode Pulse Width Modulation (PWM) controller having fixed frequency. It is basically designed for DC to DC converter purposes as well as off line applications and it requires minimum external components. UC-3843 has three different packages which will be explained later.
UC-3843 has several different features which make it ideal and useful for a lot of real life applications. These features may include trimmed oscillator for the control of accurate duty cycle, high gain amplifier and to control power MOSFET, there is a high current totem-pole output. Moreover, some ...
