5 / 12 page  Data Sheet HBT Series – Half-Brick DC/DC Converter 48V Input 60 Watt Triple Output REV. 10/01 Page 5 of 12 www.power-one.com Feature Descriptions Output Over-voltage Clamp The output overvoltage clamp consists of a separate control loop, independent of the primary control loop. This control loop has a higher voltage set point than the primary loop. In a fault condition which creates an excessive output voltage, the converter goes into “Hiccup Mode” (turns off and restarts periodically in a pre- programmed fashion), 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 mechanism that prevents catastrophic voltages from occurring on the output under any single- fault condition. Output Current Protection To provide protection in an output overload or short circuit condition, the converter is equipped with a current limiting circuit, which can protect the converter from damage under a fault condition indefinitely. At the current-limit inception point due to an output overload, the converter goes into “Hiccup Mode” and limits both the peak output current and the duration of the operation. The converter recovers automatically to its normal operation once the output overload or short circuit is removed. Enable Two enable options are available-Positive Logic and Negative Logic. Positive Logic turns the converter on when a logic-high is present at the enable pin, and turns the converter off when a logic-low is present at the enable pin. Negative Logic turns the converter off when a logic-high is present at the enable pin, and turns the converter on when a logic-low is present at the enable pin. Output Voltage Adjustment Output voltage adjustment is accomplished by connecting an external resistor between the Trim Pin and the +Vo1 or –Vo1 Pins. With an external resistor (Radj-down) between the Trim Pin and +Vo1 Pin the output voltage set point (Vo,adj) decreases. The following equation determines the required external resistor value to obtain an adjusted output voltage: Note: Output Vo1 is the only trimable output. Output Vo2 and Vo3 only follow how Vo1 is trimmed. Radj dn Vo adj D − , () A ⋅ Vo nom Vo − , adj , B − ohm ⋅ , Where Radj-down is the trim-down resistance value and A, B, and D are constants defined in Table 10. With an external resistor (Radj-up) between the Trim Pin and –Vo1 Pin the output voltage set point (Vo,adj) increases. The following equation determines the required external resistor value to obtain an adjusted output voltage: Raj up AD ⋅ Vo adj D − , () C − B − ohm ⋅ , Where Radj-up is the trim-up resistance value and A, B, C, and D are constants defined in Table 10: AB C D 4990 25500 2.5 2.5 Table 10 Output Adjustment Variables. |
