from the controller. As shown in Figure 2 the TLV431 drives current, I, F, through the optocoupler’s LED, which in turn drives the isolated transistor that is connected to the controller on the primary side of the power supply. This completes the feedback path through the isolation barrier and ensures that a stable isolated supply is maintained. 元器件型号 厂商 描述 date code 数量; 192p181x9200 : sprague/vishay: af118x200 sprague s6l1b: 174: p1812r-392k: api delevan: inductor rf ind 3.9h tol +/-10% cur 700ma sm Download a datasheet on Toshiba TLP181 Photocoupler (phototransistor output).
