UC3843 PWM Controller IC Application
The UC3843 IC is a best current Mode PWM Controller, meaning it can be used to provide a constant current by varying the output voltage to the load as like steady voltage. 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 keep constant irrespective of the current and the other is current mode control where the output current will be constant irrespective of the voltage.
The UC3843 can be used to regulate or limit current in applications like SMPS, RPS, DC-DC Converters, Line voltage regulators, etc. if you are looking for an IC with PWM signals for controlling a power switch based on the current flowing through the circuit then UC3843 might be the right choice for you.
UC3843 is a single ended 500Khz current mode PWM controller with 8.4V/7.6V ULO. Provides 100% duty cycle. The IC operating temperature is about 0 degrees Celsius to 70 degrees Celsius.
The main feature of this IC is Adjustable Switching Frequency, Current Limiting, Dead Time Control, Error Amplifier, Multi-topology.
