Description
The RFS series of converters are low profile, single output, DC/DC converters intended for SMT placement
and reflow soldering. The product provides on-board conversion of standard telecom and datacom input
voltages to isolated low output voltages. Proprietary patented manufacturing processes with full process
automation ensure optimal product quality. These are very high performance, cost effective converters with
a very small PCB footprint.

36-75V Input
1.5V, 1.8V, 2.5V, 3.3V and 5.0V Outputs
Typical Application
Output Current Limiting
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 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.
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.
Shutdown Feature
Paralleling of two converters is not possible.
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.
Output Voltage Trim
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.
Parallel Operation
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:
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).

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.

Safety Considerations
EMC Specifications
These converters feature 1500 Volt DC isolation
from input to output. The input to output resistance
is greater than 10MOhm. These converters are
provided with Operational Insulation between input
and output circuits according to EN60950 / UL1950
/ CSA60950-00. 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 enduse safety requirements must be observed. These
documents include UL60950, CSA60950-00 and
EN60950, although specific applications may have
additional requirements.
Conducted Noise:
The converters meet the requirements of level A
and level B of EN55022, CISPR22 and FCC CFR
title 47 Part 15 Sub-part J - Conducted (conducted
noise on the input terminals) using the following
circuit.
In order for the output of the converter to be
considered as SELV (Safety Extra Low Voltage) or
TNV-1, according to EN60950
/ UL1950 /
CSA60950-00, one of the following requirements
must be met in the system design:
• The converter has no internal fuse. An external
fuse must be provided to protect the system
from catastrophic failure. A fuse with a rating
not greater than 2.0A is recommended. The
user can select a lower rating fuse based upon
the inrush transient and the maximum input
current of the converter, which occurs 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, if
any.
• If the voltage source feeding the module is
SELV, the output of the converter 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 (<60V) 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.

The following instructions must be observed when
soldering the unit.
Failure to observe these
instructions may result in failure or significant
degradation of the module performance. PowerOne will not honor any warranty claims arising from
failure to observe these instructions.

The lead-frame is constructed from a high
temperature glass filled, UL94V0 flame retardant,
diallyl
ortho-phthalate
moulding
compound
commonly used for packaging of electronics
components. It has passed NASA outgassing
tests and is certified to MIL-M-14. The coefficient
of thermal expansion is equivalent to FR4.
The product is manufactured with a patented
process, which is fully automated, and ‘in-line’.
This ensures that there is no contamination or
mechanical stress on the lead-frame so that the co
planarity and solderability are maintained.

The curves below define the maximum peak reflow
temperature permissible measured on Pins 1 and
10 of the converter.
The gull wing leads are formed to ensure optimal
solder joint strength and structure. Furthermore
they facilitate visual inspection (manual or
automatic). The leads are formed from a 97% Cu
alloy plated with Cu and Sn 90. This material is
commonly used in the manufacture of integrated
circuits. It has good corrosion resistance and
exhibits the nobility inherent to all high copper
alloys. Unlike brasses, this material is essentially
immune to stress corrosion cracking.
It also
exhibits excellent solderability. It is readily wetted
by solders and performs well in standard
solderability tests. (Dip of Class II or better).

Pick & Place Assembly:
The product is designed with a large flat area in the
center of the top surface to serve as a pick up point
for automated vacuum pick and place equipment.
The ‘open board’ construction of the unit ensures
that weight is kept to a minimum. However due to
the relatively large size of the component, a large
nozzle (> 4 .0mm, depending on vacuum pressure)
is recommended for picking and placing.
The unit may also be automatically handled using
‘odd-form’ placement equipment, with mechanical
grippers. For this type of equipment the end edges
of the device, which have no leads and also feature
the greatest dimensional accuracy, should be used
as pick-up points.
