Set VO according to the following equation: VO= VREF (1+R1/ R2)+ IREF R1 Choose the value for RB as follows: The maximum limit for RB should be such that the cathode current( IK) is greater than the minimum operating current (60µA) at VIN (MIN) . The minimum limit for RB should be such that the cathode current (IK) does not exceed 100mA under all load conditions, and the instantaneous turn-on value for IK does not exceed 150mA . Both of the following conditions must be met : RB,MIN ≥ VIN(MAX) / 150mA ( to limit instantaneous turn-on IK) RB,MIN ≥ VIN(MAX) - VO / IO (MIN) + 100mA (to limit IK under normal operating conditions) • • 3) Copyright  ANPEC Electronics Corp.
