Typical Application
This series of converters does not require any
external
components
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 1μF, quality electrolytic / ceramic capacitor is
recommended for this purpose.
For output decoupling it is recommend connecting
a 1μF 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 –Vin 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
-Vin 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
+Vin pin.
The user must take care to ensure that the pin
reference for the control is connected close to the -
Vin 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 (Tc). To ensure reliable long term
operation of the converters, and to comply with
safety agency requirements, Power-One limits
maximum allowable case temperature (Tc) to
100°C (see Mechanical Drawings).
for
proper
operation.
Output Current Limiting
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 25ms until the
overload has cleared.
Parallel Operation
Paralleling of two converters is not possible.
Output Voltage Trim
The trim feature allows the user to adjust the output
voltage from the nominal.
Output voltage can be adjusted by an external
resistor. To increase Vo a resistor should be
connected between pins 2 and 3. To decrease Vo a
resistor should be connected between pins 1 and 3.
To
increase
Vo:
Rext = (A – (D x Vout)) / ( Vout – Vout.Nom)
To
reduce
Vo:
Rext = ((B x Vout) - C) / ( Vout.Nom - Vout)
Where Vout is the desired output voltage

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.
