Abstract :
In this study, the design and typical applications of an isolation feedback generator circuit were presented. The circuit was processed in 40 V SOI bipolar process technology, and integrated the precision reference source, the high-frequency oscillator, the error amplifier, and the complete modulation module, and simplified the design of the isolation and closed-loop feedback of primary switching power supply. As the power conversion technology develops continuously, the circuit is suitable especially to high-reliability, high-performance, and radiation hardening applications.
