The isolated AC-to-DC Flyback converter is the most commonly used power supply type for home and industrial devices. Fear of the main voltage and complexity of calculations cause electronic beginners and enthusiasts to procrastinate DIY such circuits. This project introduces an AC-to-DC flyback switching power supply that converts universal 50Hz AC input (85V-260VAC) to 12VDC-0.5A (6W) using the minimum components in the BOM, both price and quantity.
The transformer’s ferrite core is RM6 and DK106 is the controller chip. The inductance of the primary winding of the transformer is 2mH and the switching frequency is 65KHz. Output regulation is done through a Zener diode, and the controller chip does not need any external supply rail or an auxiliary winding on the transformer; making it a beginner-friendly DIY circuit to learn and experience.

85V-265V wide-range AC power input.
Double chip design with Bipolar Junction Transistor (BJT) to save cost.
Large-scale MOS digital circuit design with E class BJT driving, so that to enhance its High Voltage Resistance Capability
Self-power supply circuit design, no need for additional IC to supply electricity to reduce component and cost
Internal integrated constant high voltage current driving circuit, no need for additional resistance.
Over-current, Overloading, over-temperature, over-voltage, Output short circuit, and photo-coupler Failure Protection
Internal Ramp Compensation circuit to keep the stability of the circuit in low voltage and high-power conditions
Internal PMW oscillation circuit with Frequency jittering control to keep EMC characteristics.
Internal Frequency Conversion. Frequency-down in low load conditions complies with the European Standard, and also reduces the output voltage ripple
Ramp current drive circuit included to reduce IC power loss and raise circuit efficiency.
