The most effective combination of external I/O capacitors will be a function
of your line voltage and source impedance, as well as your particular load
and layout conditions. Our Applications Engineers can recommend potential
solutions and discuss the possibility of our modifying a given device’s inter-
nal fi ltering to meet your specifi c requirements. Contact our Applications
Engineering Group for additional details.
Input Overvoltage and Reverse-Polarity Protection
UNR 18-33W Series DC/DC converters do not incorporate either input over-
voltage or input reverse-polarity protection. Input voltages in excess of the
listed absolute maximum ratings and input polarity reversals of longer than
"instantaneous" duration can cause permanent damage to these devices.
On/Off Control Functionality
The On/Off Control pin has an internal 5kΩ pull-up resistor to +V
driven with any logic circuit capable of meeting the following requirements:
Logic "0" = 0 to +0.8V; Logic "1" = +2.0V to +V
I
transistor can be used. The drive circuit should be rated for more than 5.5V.
Applying a voltage to pin 2 when no input power is applied to the converter
can cause permanent damage to the converter.
