摘要
本文阐述了使用OB2212AP芯片设计隔离的12V/200mA、5V/200mA两路输出,采用原边反馈的反激式开关电源。OB2212AP具有一般的过流、过压、欠压保护等功能,在90~264VAC的电压输入下,开放式能输出功率12W,密闭式可输出功率8W。全文以洗衣机上的电路板开发为例,使用相关的检测仪器对调试板上的电源进行性能、信号的检测,最后得到了预期的结果。
This paper expounds the design of isolated two routes to output,12V/200mA and 5V/200mA with OB2212AP chip,and the design structure adopts the PSR(Primary-side sending and Regulation) flyback switching power supply.OB2212AP has the general functions of over-current,overvoltage and low-voltage protection,under the 90-264VAC input voltage,the open one can output the power of 12W and the closed one can output the power of 8W.This paper takes the circuit board development of the washing machine,for example,and uses the correlative detecting instrument to detect the performance and signal of the power supply on the debugging board,finally,it gets the expected results.
