Application and Auxiliary Functions
This series of converters does not require any external
components for proper operation. However, if the
distribution of the input voltage to the converter
contains significant inductance, a capacitor across the
input terminals may be required to stabilize the input
voltage. A minimum of 1 μF, quality electrolytic /
ceramic capacitor is recommended for this purpose.
For output decoupling it is recommend connecting a
1 μF ceramic capacitor directly across the output pins
of the converter.
Shutdown Feature
The remote control pin functions as a normal soft
shutdown. It is referenced to the –Vi pin. With positive
logic, when the remote control pin is pulled low, the
output is turned off and the unit goes into a very low
input power mode.
An open collector switch is recommended to control
the voltage between the remote control pin and the
–Vi pin of the converter. The remote control pin is
pulled up internally, so no external voltage source is
required. The user should avoid connecting a resistor
between the remote control pin and the +Vi pin.
The user must take care to ensure that the pin
reference for the control is connected close to the –Vi
pin. The control signal must not be referenced ahead
of EMI filtering, or remotely from the unit. If the remote
control pin is not used, it can be left floating.
Thermal Considerations
The converter is designed for natural or forced
convection cooling. The output power of the converter
is limited by the maximum case temperature (T

Output Current Limitation
When the output is overloaded above the maximum
output current rating, the voltage will start to reduce to
maintain the output power to a safe level. In a
condition of high overload or short-circuit, where the
output voltage is pulled below approximately 30% of
Vo.Nom, the unit will enter a ‘Hiccup’ mode of
operation. Under this condition the unit will attempt to
restart, approximately every 25 ms, until the overload
has cleared.
Output Voltage Adjustment
The trim feature allows the user for adjusting the
output voltage by means of an external resistor. To

Note: When the output voltage is trimmed up, the
output power from the converter must not exceed its
maximum rating. This is determined by measuring the
voltage on the output pins, and multiplying it by the
output current.
