Design Considerations
Grounding Considerations
For the QW modules, the case is internally connected
to the V
Input Source Impedance
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the power mod-
ule. If the input source inductance exceeds 4 µH, a
33 µF electrolytic capacitor (ESR < 0.7 ohm at 100 kHz)
mounted close to the power module helps ensure sta-
bility of the unit.
Safety Considerations
QW
For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standard,
i.e., UL60950, CSA C22.2 No. 60950-00, and VDE
0805 (IEC60950).
If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75 Vdc), for the module’s output to be considered
meeting the requirements of safety extra-low voltage
(SELV), all of the following must be true:

both the input and output pins are to be kept floating.
The input pins of the module are not operator acces-
sible.
Another SELV reliability test is conducted on the
whole system, as required by the safety agencies, on
the combination of supply source and the subject
module to verify that under a single fault, hazardous
voltages do not appear at the module’s output.

Feature Descriptions
Overcurrent Protection
To provide protection in a fault (output overload) condi-
tion, the unit is equipped with internal current-limiting
circuitry and can endure current limiting for an unlim-
ited duration. At the point of current-limit inception, the
unit shifts from voltage control to current control. If the
output voltage is pulled very low during a severe fault,
the current-limit circuit can exhibit either foldback or
tailout characteristics (output-current decrease or
increase). The unit operates normally once the output
current is brought back into its specified range.
Remote On/Off
Two remote on/off options are available. Positive logic
remote on/off turns the module on during a logic-high
voltage on the remote ON/OFF pin, and off during a
logic low. Negative logic remote on/off, device code
suffix “1,” turns the module off during logic-high voltage
and on during a logic low.
To turn the power module on and off, the user must
supply a switch to control the voltage between the
on/off terminal and the V
switch may be an open collector or equivalent (see
Figure 4). A logic low is V

During a logic high, the maximum V

leakage current of the switch at V

during a logic low is 1 mA. The switch
