innoSwitch3 UVLO

   Set the line sense resistance value based on the brown-in voltage. They are typically connected after the bridge rectifier. Typical total value is 3.8 ~ 4.2 MΩ. R_LS is approximately equal to V_BROWN-IN × 1.414 / I_UV+.


Brown-Out Actual
   During brown-out, the power supply will inhibit switching when the brown-out threshold current falls below the I_UV- threshold.

Line Overvoltage
   This is the input AC voltage at which the power supply will instantaneously stop switching once the overvoltage threshold (I_OV+) is exceeded, switching will be re-enabled when switching the line overvoltage hysteresis (I_OV(H)) level is reached. Line OV voltage is approximately equal to I_OV+ × R_LS / 1.414.
