NTF Series
Isolated 1W Wide Input DC/DC Converters
APPLICATION NOTES
Recommended input & output capacitors
Although these converters will work without external capacitors, they are
Value
necessary in order to guarantee the full parametric performance over the full
line and load range. All parts have been tested and characterized using the
following values and test circuit.

ON/OFF Pin
This provides an OFF function, which puts the converter into a low power mode. When the pin is un-connected, the converter is on. The circuit used must be able to sink a peak
curent of 50mA to guarantee turning the converter off. The circuit should be an open collector arrangement, an example circuit is shown below. Voltages should not be applied
directly to the ON/OFF pin. The BC547 should be ?tted close to the NTF ON/OFF pin to prevent the addition of excess wiring capacitance.

When the output voltage is trimmed up, output current must be derated so that the maximum output power is not exceeded.
