Description
The XY6112 is current-mode PWM controller. Built-in high-voltage power management, wide voltage AC85 – 350V Fan Provides up to 12W of continuous output power within the circumference. Cost-effective production of bipolar control chip production process, combined with high Pressure power tube integrated package to save the overall cost of the product to the maximum extent. The power supply controller can work in a typical Flyback topology to form a simple AC / DC converter.
