The UCC28730-Q1 isolated-flyback power supply controller is a cutting-edge device that offers constant-voltage and constant-current output regulation without the need for an optical coupler. With a minimum switching frequency of 30 Hz, this controller boasts ultra-low no-load power consumption of less than 5 mW, making it a highly energy-efficient solution for power supply applications. By leveraging information from the primary power switch and an auxiliary flyback winding, the UCC28730-Q1 ensures precise control over output voltage and current, resulting in stable and reliable performance
