This control loop has a higher voltage setpoint than the primary loop. In a fault condition the converter goes into “Hiccup Mode”, and the output overvoltage clamp ensures that the output voltage does not exceed Vo,clamp,max. This secondary control loop provides a redundant voltage-control that reduces the risk of output overvoltage. Output Current Protection To provide protection in an output overload or short circuit condition, the converter is equipped with current limiting circuitry and can endure the fault condition for an unlimited duration. At the point of current-limit inception, the converter goes into “Hiccup Mode”, causing the output current to be limited both in peak and duration. The converter operates normally once the output current is brought back into its specified range. Enable (Optional) Two enable option are available. Positive Logic Enable, no suffix, and Negative Logic Enable, suffix “N”. Positive Logic Enable turns the converter on during a logic-high voltage on the enable pin, and off during a logic-low. Negative Logic Enable turns the converter off during a logic-high and on during a logic-low. Output Voltage Adjustment Output voltage adjustment is accomplished by connecting an external resistor between the Vadj Pin and either the +Sense or –Sense Pins. With an external resistor between the Vadj Pin and -Sense Pin (Radj-down) the output voltage set point (Vo,adj) decreases (see Figure 11). The following equation determines the required external resistor value to obtain an adjusted output voltage: Radj_down 100 %Vo, adj 2 . kohm Where Radj-down is the resistance value and %Vo,adj is the percent change in the output voltage. With an external resistor between the Vadj Pin and +Sense Pin (Radj-up) the output voltage set point (Vo,adj) increases (see Figure 12). The following equation determines the required external resistor value to obtain an adjusted output voltage: Radj_up Vo.

Heat-dissipating components are thermally coupled to the case. Heat is removed by conduction, convection and radiation to the surrounding environment. Proper cooling can be verified by measuring the case temperature. Heat Transfer Characteristics Increasing airflow over the converter enhances the heat transfer via convection. Figure 13 shows the maximum power that can be dissipated by the converter without exceeding the maximum case temperature versus local ambient temperature (TA) for natural convection through 2.0 m/s (400 ft/min). Systems in which these converters are used generate airflow rates of 0.25 m/s (50 ft/min) due to other heat dissipating components in the system. Therefore, the natural convection condition represents airflow rates of approximately 0.25 m/s (50 ft/min). Use of Figure 13 is shown in the following example. Example What is the minimum airflow required for an 033F40H operating at 48 V, an output current of 25 A, and maximum ambient temperature of 55 ºC. Solution: Given: Vi = 48 V, Io = 25 A, TA = 55 ºC. Determine PD (Figure 16): PD = 13 W. Determine airflow (Figure 16): v = 1.0 m/s (200 ft/min) BK60C SERIES Power Derating Curve 30 25 20 15 10 5 0 25 30 35 40 45 50 55 60 65 70 75 80 85 90 Nat.
