Manufacturer:71 Description:Current sense input for +3.3V output. This pin is connected to the current sensing resistor or inductor. You can define OCP offset voltage for +3.3V by using RI resistor externally. If you connect 62kΩ at pin 8 to ground, the reference current(Iref1) should be 20uA. After that , you can make a constant OCP offset voltage(Voffset=Roffset*5*20uA). In case the voltage drop(IO.33*Rs) of the sense resistor or inductor is larger than offset voltage, after OCP delay time the main SMPS is turned off. So the over current level is determined by the following equation. IO.33=Voffset/Rs. |
