Typical Application
KOhm
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 stabilise the input voltage. A minimum
of 1µF, quality electrolytic / ceramic capacitor is
recommended for this purpose.
For output decoupling it is recommended to
connect, directly across the output pins, a 1µF
ceramic capacitor (for 3.3V and 5V outputs) or a
0.27µF ceramic capacitor (for 12V outputs).

It is possible to synchronize the switching
frequency of one or more converters to an
external symmetrical clock signal.
It is
recommended that the signal be driven by a TTL
compatible output. The rise time of the clock
signal should be less than 10ns.
If the
synchronization feature is not used, it should be
left open circuit.
An external resistor can program the input voltage
at which the converter switches on. The voltage
at which the unit switches off is typically 1V below
the turn-on input voltage (Vion).
The characteristic curves below shows the typical
resistor values required to achieve adjustment of
turn-on input voltage (Vion).

Output Current Limiting
Output Voltage Trim
Note: For setting nominal output voltage pin 8
must be connected to pin 9.
The trim feature allows the user to adjust the
output voltage from the nominal. This can be
used to accommodate a different requirement or
to do production margin testing.
Output voltage can be adjusted by an external
resistor. If pin 8 and pin 9 are not connected
together the output will decrease to a low value.
To increase Vo a resistor should be connected
between pin 8 / 9 and pin 17 ( -Vin). To decrease
Vo, a resistor should be connected between pin 8
and 9 (NOR).
To increase Vo:
Radj = A x (B - Vd) / (Vd - Vo) kΩ
Where: Vd = Desired output voltage
Vo = Nominal output voltage.
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 100ms until the overload has
cleared.
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
110°C (see Mechanical Drawings).
To reduce Vo:
Remote Control Feature
Radj = C x (Vo - Vd) / (Vd - D) kΩ
Where: Vd = Desired output voltage
Vo = Nominal output voltage.

Notes:
1. 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 output voltage
on the output pins, and multiplying it by the
output current.
2.
The trim feature allows the generation of
additional standard voltages such as ±15V
from the ±12V model.
Parallel Operation
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.
Paralleling of two converters is possible by direct
connection of the output voltage terminal pins.
The load regulation characteristic is designed to
facilitate current sharing (typically ± 20%).

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 end-use safety
requirements must be observed.
These
documents include UL60950, CSA60950-00 and
EN60950, although specific applications may
have additional requirements.
Conducted Noise:
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.

input terminals) without any external components.
The results for this solution are displayed below.
To meet level B for the above standards it is
necessary to fit a 3.3µF ceramic capacitor across
the input terminals.

Surface Mount Assembly
The lead-frame is constructed for 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 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).
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 product is shipped in JEDEC trays to
guarantee preservation of the co-planarity and
enable fully automated assembly in the final
application.

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.
