www.irantk.ir XY6112 Cost-effective off-line switching power supply controller - Shanghai Vision Institute of Electronic Technology Co., Ltd. Page 1 of 13 version: 1.1 2008 I. Overview XY6112 for high-performance , 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. IC's internal circuitry can be used to start the power switch itself Amplification to complete start , greatly minimizes the power consumption of the starting resistor ; from the IC when the output power of the small Automatically reduce the operating frequency , in order to achieve a very low standby power consumption ; patent switch drive circuit operates in the critical saturation State, improve the efficiency of the system, the system can easily meet the standby power consumption and efficiency on "Energy Star" Certification requirements. Down in achieving standby while limiting the operating frequency into the audio range, to prevent audible noise generation . 4-12V operating voltage range provides easy VCC voltage design space, but when VCC reaches 12V chip protection, Or limit the output optocoupler feed...
