Working Principles
The UC2524ADWTRG4 is a high-performance PWM controller designed for power management applications. It operates by regulating the duty cycle of a power switch to control the output voltage. The error amplifier compares the feedback voltage with a reference voltage, generating an error signal that drives the power switch. By adjusting the duty cycle, the controller maintains the desired output voltage.
The timing resistor and capacitor connected to the RT/CT pin determine the switching frequency of the power switch. The soft-start feature gradually increases the duty cycle during startup to prevent excessive inrush current. The synchronization input allows multiple controllers to operate in sync for higher power applications.
