Description
- The peripheral design is simple.
- Fix the primary peak current and set the output constant current point through the transformer primary-secondary turns ratio;
- Set an FB resistor to set the output constant voltage point. In order to achieve the ultimate simplification of system cost,
- ICW3667 has a built-in startup circuit, and the peripheral does not need a startup resistor.
- Built-in FB under-bias resistor, fixed peak current to cancel the current limiting resistor
- Use self-powered method to cancel the auxiliary winding VCC power supply diode.
- Built-in input line voltage compensation function
- Fixed output cable compensation method for output voltage compensation
- Integrated a variety of protection functions, including vCC clamping/undervoltage protection, output short circuit protection, and over-temperature protection.
