Power-One FEATURE DESCRIPTIONS Output Overvoltage Clamp The output overvoltage clamp consists of a separate control loop, independent of the primary control loop. 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 Two enable options are available. Positive Logic Enable and Negative Logic Enable. 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. REV. JUN 27, 2003 Page 7 of 12 HWD DC/DC Series Data Sheet Output Voltage Adjustment Output voltage adjustment is accomplished by connecting an external resistor between the Trim Pin and either the +Vo1 or –Vo1 Pins. With an external resistor between the Trim Pin and +Vo1 Pin (Radj-down) the output voltage set point (Vo,adj) decreases. The following equation determines the required external resistor value to obtain an adjusted output voltage: Radj, dn= , adj - D) A [ Vo(Vo, nom -B ] - Vo, adj ohm Where Radj-down is the resistance value and A, B, and D are defined in Table 7. With an external resistor between the Trim Pin and –Vo1 Pin (Radj-up) the output voltage set point (Vo,adj) increases. The following equation determines the required external resistor value to obtain an adjusted output voltage: Radj, up= [ (Vo, adjA •-DD) - C - B ] ohm Where Radj-up is the resistance value and A, B, C, and D are defined in Table 12. Table 12.Output Adjustment Variables Output Vo1 Vo2 A 4990 4990 B 2000 2000 C 2.5 0.8 D 2.5 2.5 THERMAL CONSIDERATIONS The power converter operates in a variety of thermal environments: however, sufficient cooling should be provided to help ensure reliable operation of the converter. 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 4 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 400 ft/min. Systems in which these converters are used generate airflow rates of 50 ft/min due to other heat dissipating components in the system. Therefore, the natural convection condition represents airflow rates of approximately 50 ft/min. Use of Figure 4 is shown in the following example. Example What is the minimum airflow required for the device operating at 24 V, an output power of 60 W, and maximum ambient temperature of 60 ºC. Solution: Given: Vi = 24 V, Po = 60 W, TA = 60 ºC. Determine PD (Figure 4): PD = 13 W. Determine airflow (Figure 4): v = 200 ft/min REV.
