Working Principle

The S-8520A36MC-AVVT2G operates through a unique dual architecture, incorporating both synchronous rectification control and logic controlled output and space control. It is constructed using a voltage reference circuit and a Peizo oscillator to regulate its switching frequency. The S-8520A36MC-AVVT2G controller first starts to regulate the output voltage during the startup phase and then uses synchronous rectification to convert the two winding\'s peak voltage into the output current of the load. The controller works in the alternating peak current (ABA) mode at all times, ensuring optimum efficiency at all times. The logic controlled output and space control combines digital and analog controls for better accuracy and performance. In standby mode, the S-8520A36MC-AVVT2G will maintain a low quiescent current. This is achieved by using the dynamic voltage switch and voltage reference circuit. The voltage reference circuit adjusts the quiescent current while maintaining the output and input voltages. A switchable leakage current mode is also provided which can reduce the operating current up to 20%.

Conclusion

The S-8520A36MC-AVVT2G is a high performance switching controller, ideal for a wide range of applications. Its dual architecture combines synchronous rectification and logic controlled output with space control. Its efficiency and low quiescent current, combined with its high switching frequency and accurate slope compensation, make it an excellent choice for both general purpose and high-end applications.
