Working Principles

The UC3823AN is a pulse-width modulation (PWM) controller IC used for power management. It regulates the power flow by controlling the duty cycle of the output waveform. The input voltage is converted into a high-frequency square wave, which is then filtered and smoothed to provide a stable output voltage. The feedback loop compares the output voltage with a reference voltage and adjusts the duty cycle accordingly to maintain the desired output voltage.
