Working Principles

The UC2524ADWG4 is a pulse-width modulation (PWM) controller that regulates the power delivered to a load. It operates by comparing a feedback voltage with a reference voltage to generate a control signal. This control signal determines the duty cycle of the output waveform, which in turn controls the average power delivered to the load. By adjusting the duty cycle, the UC2524ADWG4 can regulate the output voltage or current as required.
