... APPLICATION NOTES 1. OUTPUT DE-RATING The operating case temperature range for VHB100W is -40 ~ +100°C. When operating the VHB100W series, proper derating or cool- ing is needed. The maximum case temperature under any operating condition should not exceed 100°C. Power Dissipated vs Ambient Temperature and Air Flo w Ambient Temperature ,Ta(Deg ...

... The fuse rating will depend on the input range and should allow for the maximum current at the lowest input volt- age, as shown in this equation: Ipeak = 150%*Pout/(η η *Vmin). In the previous example of VHB100W-Q24-S5, the peak input current at 9V was calculated to be 19. fuse may be suitable for this application. Make sure the fuse voltage rating is higher than the maximum input voltage. ...

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 100°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 ...

... PART NUMBER: VHB100W 12. OUTPUT SERIES CONNECTIONS Two or more converters can be connected in series to obtain a higher output voltage. To prevent output reverse biasing each other in case of a short, add a Schottky diode on each output in reverse polarity, as shown in the diagram. In the event of a short, the con- verters will forward-bias the diodes and the output reversal will be limited to one diode drop (about 0 ...

... PART NUMBER: VHB100W 15. INPUT FILTERING AND EMI INTERFERENCE The VHB100W converters have input capacitors that control input current ripple and the associated EMI interference. However, it has not been tested to a formal standard for conducted emissions. Additional filtering may be needed to ensure compliance to an EMI standard ...

Conduction EN55022 class B Model No. VHB100W-Q24-S28 VHB100W-Q48-S28 note: The recommended components are a starting point but not guaranteed for meeting these EMI requirements. More or less filtering may be required for a specific application or to meet other EMI standards, e.g.MIL-STD-461 16. OUTPUT FILTERING The converter has built-in capacitors at the output to control ripple and noise. If desired, additional output capacitance can be introduced at the input to the powered equipment. Recommended starting point: one 10μ ...
