SFS Series Data Sheet
43W SMT DC-DC Converters, 1.5 – 5 V Output
Output Voltage Adjust
This feature allows the user to adjust the output
voltage. Output voltage can be adjusted using an
external resistor. To increase V o a resistor should be
connected between pin 15 and pins 17 & 18. To
decrease V o a resistor should be connected between
pin 15 and pins 1 & 2.
To increase V o :
Safety
These converters are tested with 1500 VDC from input
to output. The input-to-output resistance is greater
than 10 M ? . These converters are provided with Basic
Insulation between input and output. Nevertheless, if
the system using the converter needs to receive
safety agency approval, certain rules must be followed
in the design of the system. In particular, all of the
creepage and clearance requirements of the end-use
system must be observed.
R ext = (A – (D × V o )) / (V o – V o nom ) [ Ω ]
In order to consider the output of the converter as
To reduce V o :
R ext = ((B × V o ) – C) / V o nom – V o ) [ Ω ]
SELV (Safety Extra Low Voltage) or TNV-1, according
to IEC/EN 60950-1 and UL/CSA 60950-1, the follow-
ing requirements must be met in the system design:
? Fuse: As the converter has no internal fuse, an

external fuse must be provided to protect the
system from catastrophic failure. We recommend a
fuse with a rating not greater than 2.0 A. The user
can select a fuse with lower rating based upon the
maximum inrush transient and the maximum input
current at the minimum input voltage. Both input
traces and the chassis ground trace (if applicable)
must be capable of conducting a current of 1.5
times the value of the fuse without opening. The
fuse must not be placed in the grounded input line.
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.
Parallel Operation
Paralleling of two converters is not possible.
Synchronization
It is possible to synchronize the switching frequency of
one or more converters to an external symmetrical
clock signal. Consult factory for full application details,
if this option is required.
? If the voltage source feeding the converter is
SELV, TNV-1, or TNV-2, the output of the con-
verter is considered SELV and may be grounded
or ungrounded.
? The circuitry of the converter may generate
transients, which exceed the input voltage. Even if
the input voltage is SELV (<60 V), the components
on the primary side of the converter may have to
be considered as hazardous. A safety interlock
may be needed to prevent the user from accessing
the converter while operational.
