... APPLICATION NOTES 1. OUTPUT DE-RATING The operating ambient temperature range for VHK200W is -40 ~ +100°C, with the actual output power subject to the following de-rating curves at free-air convection and at forced air conditions. To ensure long-term reliability important to ensure proper cooling at the worst operating conditions. ...

PART NUMBER: VHK200W VHK200W-Q48 Power Derating Curves @ Nominal Input 120% 100% 80% 60% 40% 20 INPUT VOLTAGE RANGE It is important to ensure the input voltage measured at the converter input pins is within the range for that converter. Make sure wire losses and voltage ripples are accounted for. One possible problem is driving the converter with a linear unregulated power supply. ...

... PART NUMBER: VHK200W 10. OUTPUT OCP AND SHORT-CIRCUIT PROTECTION Output overload and short circuit conditional will cause the output voltage to decline or shutdown altogether. is not over 105°C, the output recovers automatically when the short or OCP conditions are removed. In the case of slight overloading, the output voltage may not shut down, but the converter may build up heat over time, causing over-temperature shutdown ...

... INPUT FILTERING AND EMI INTERFERENCE The VHK200W converters have input capacitors that control input current ripple and the associated EMI interference. However, they have not been tested to a formal standard for conducted emissions. Additional filtering may be needed to ensure compliance to an EMI standard ...
