AC/DC power supply controller ICs target primary-side regulated flyback converters. These power supply ICs are suitable for applications with 5~80W ACDC converters. A high-voltage current source enables a fast and efficient start-up. Advanced light-load modes are deployed to reduce both controller and system power consumption at no load and light load. We hope these power supply ICs are an ideal fit for your application needs and can simplify your design with specific power control ICs.
