ISOLATION VOLTAGE
To verify the integrity of the isolation a test voltage is applied for a specified time across a component that is designed to
provide electrical isolation. This test is known as ’High Pot Test’, ’Flash Tested’, ’Withstand Voltage’, ’Proof Voltage’,
’Dielectric Withstand Voltage’ or ’Isolation Test Voltage’.
All isolated Power Modules are 100% production tested at their stated isolation voltage. This is 3 kVDC for 60 seconds.
The isolation test voltage indicated in this data sheet is for voltage transient immunity only. It does not allow this part to be
used within a safety isolation system.
The module will function properly with several hundreds of volts applied continuously across the isolation barrier, however
surrounding components must be individually analyzed to ensure proper insulation. Isolation measures must be taken into
account to prevent any user-accessible circuitry from causing harm.
14.1 Dielectric Test Setup (High Pot Test)
Connect all input and output terminals together (see figure below) before connecting the supply voltage. When testing, set
the cut-off current to 1mA with a test voltage of 3kVDC and test time of 60s.

14.2 Repeated High-Voltage Isolation Testing
A repeated high voltage test of a barrier component degrades its isolation capabilities.
The primary and secondary windings within this transformer are enameled (coated) but do not possess additional isolation.
Typically, parts can withstand multiples of their stated test voltage and still perform optimally. The magnet wire coating
can degrade over time due to chemical reactions that occur at high voltages. We recommend keeping high voltage isolation
testing to a minimum to better protect the isolation between the windings. If repeated high voltage isolation testing is
required, consider reducing the voltage by a significant amount e.g. 20% from the test voltage stated within the datasheet
These safety concerns are equally applicable to components that utilize functional isolation beyond wire coating (i.e.
physical barriers or spacing).

CIRCUIT DESCRIPTION
The MagI3 C power module 1769205141 is based on full bridge topology whereas the MagI3 C power modules
1769205041 / 1769205241 / 1769205341 are based on a push-pull converter. All modules have an integrated IC,
rectifying diodes, input and output capacitors and a transformer.
Since there is no feedback path from the output to the input, the duty cycle is fixed at 50% and is independent of the load
(zero load to full load). The output voltage is unregulated and defined by the turns ratio of the transformer.

PROTECTION FEATURES
18.1 Short-Circuit Protection (SCP)
The modules are continously output short-circuit protected. The protection is realized via comparing the drain voltages of
the MOSFETs to a certain internal reference. During a short circuit situation the output voltage is pulled low. The output
voltage recovers to its nominal value after the error is resolved.

DESIGN EXAMPLE
The design example shows a possible solution for 3.3V (1769205041), 5V (1769205141), 12V (1769205241) and 24V
(1769205341) to 5V with a max. Iout of 0.2A. All of the necessary components to fullfill the requirements of the CISPR 32
EMI conducted- and radiated-emissions tests are included in the design example. It passes the conducted emissions class
B with 0.8m input- and 1m output lines and passes the radiated emissions class B in a FAR at 3m measurement distance
with 0.8m horizontal, 0.8m vertical input- and 1m horizontal outputlines. In the final application filter components may be
omitted depending on the requirements.
19.1 Layout
Figure 19: 1769205x41 layout recommendation.
The layout above has been evaluated to provide the optimal performance in terms of transient response, efficiency, ripple and
EMI. The design footprint can be reduced at the expense of performance in these parameters. The following recommendation
should be followed when designing the layout:
1. The input capacitor should be placed as close as possible to the +VIN and -VIN pins of the device.
2. The output capacitor should be placed as close as possible to the +VOUT and -VOUT pins of the device.
3. The Y-capacitor should be placed as close as possible to the +VIN and -VOUT pins of the device.

APPLICATION CONSIDERATIONS
20.1 Primary Side Parallel Connection
A standard industrial configuration is, that the power modules are supplied by a dc bus voltage. Multiple 1769205x41 can
be connected to one dc bus as shown in the figure below.
The outputs must not be connected in parallel to each other and could have individual voltages VOUT1 and VOUT2 . For serial
connection of the output see also ’Secondary Side Serial Connection’.
In case of using long supply lines or different wire length for each 1769205x41 it is recommended to decouple each power
module with an additional LC filter (see schematic below). The decoupling LC filter is also recommended if the supplying dc
bus has a high impedance so that high voltage swings at the input of each power module might be present.

Figure 21: Decoupling for primary side parallel connection.
As a starting point for the decoupling filters, use the values of the reference filters - see also ’Radiated And Conducted
Emissions (With Input Filter)’. The final appropriate filter for the application has then to be evaluated under operation in the
target application by checking e.g. the change of the input ripple voltage.

20.2 Secondary Side Serial Connection
To generate a higher output voltage it is possible to put the outputs of the 1769205x41 in series. It is common practice to
connect an additional capacitor between the +VOUT and -VOUT.

In case of using long supply lines or different line length for each 1769205x41 it is recommended to decouple each power
module with an additional LC filter. The decoupling LC filter is also recommended if the supplying dc bus has a high impedance
so that high voltage swings at the input of each power module could be present. As initial values, the EMI filter shown for
every part number can be used. See also ’Primary Side Parallel Connection’.

20.3 Generating Complementary Output Voltages
Another common requirement in industrial applications is to provide a complementary voltage (±5V). This can be easily
implemented by using two 1769205x41 modules according to the schematic below. It is a common practice to connect an
additional capacitor across each output voltage.

20.4 Reverse Polarity Protection
A simple way of creating an input reverse polarity protection is to place a diode in series with the positive input line. Due to
the forward voltage drop of the diode the application efficiency drops.

HANDLING RECOMMENDATIONS
1. The power module is classified as MSL1 (JEDEC Moisture Sensitivity Level 1) and doesn´t requires special handling due
to moisture sensitivity (JEDEC J-STD033).
2. Parts have unlimited floor life according to JEDEC J-STD033.
3. Maximum numbers of reflow cycles is two.
4. For minimum risk, solder the module in the last reflow cycle of the PCB production.
5. The component lead material is copper (Cu) and the lead finish is ENEPIG (NiPdAu).
6. For solder paste use a standard SAC Alloy such as SAC 305, type 3 or higher.
7. The profile below is valid for convection reflow only
8. Other soldering methods (e.g. vapor phase) are not verified and have to be validated by the customer at their own risk

PCN, Major change
To improve the processability, Würth
Elektronik has expanded the reflow
solder profile to align with the JEDEC
J-STD020E industry standard for reflow
soldering. As a datasheet information
amendment, Würth Elektronik has
changed the specified switching
frequency to create a better
understanding between the internal and
external switching frequency of the
topology and to justify the shown EMC
diagrams. This is a datasheet correction
only. There will be no change in form, fit,
function, quality or reliability of the
product. All date codes will be affected
by this change.

IMPORTANT NOTES
General Customer Responsibility
Some goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain statements regarding general
suitability for certain application areas. These statements about suitability are based on our knowledge and experience of
typical requirements concerning the areas, serve as general guidance and cannot be estimated as binding statements
about the suitability for a customer application. The responsibility for the applicability and use in a particular customer
design is always solely within the authority of the customer. Due to this fact it is up to the customer to evaluate, where
appropriate to investigate and decide whether the device with the specific product characteristics described in the product
specification is valid and suitable for the respective customer application or not. Accordingly, the customer is cautioned to
verify that the datasheet is current before placing orders.
Customer Responsibility Related to Specific, in Particular Safety-Relevant, Applications
It has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the
usual lifetime cannot be completely eliminated in the current state of the art, even if the products are operated within the
range of the specifications. In certain customer applications requiring a very high level of safety and especially in customer
applications in which the malfunction or failure of an electronic component could endanger human life or health it must
be ensured by most advanced technological aid of suitable design of the customer application that no injury or damage is
caused to third parties in the event of malfunction or failure of an electronic component.
Best Care and Attention
Any product-specific notes, warnings and cautions must be strictly observed. Any disregard will result in the loss of warranty.
Customer Support for Product Specifications
Some products within the product range may contain substances which are subject to restrictions in certain jurisdictions
in order to serve specific technical requirements. Necessary information is available on request. In this case the field sales
engineer or the internal sales person in charge should be contacted who will be happy to support in this matter.
Product R&D
Due to constant product improvement product specifications may change from time to time. As a standard reporting
procedure of the Product Change Notification (PCN) according to the JEDEC-Standard we inform about minor and major
changes. In case of further queries regarding the PCN, the field sales engineer or the internal sales person in charge should
be contacted. The basic responsibility of the customer as per Section 1 and 2 remains unaffected.
Product Life Cycle
Due to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of
products. As a standard reporting procedure of the Product Termination Notification (PTN) according to the JEDEC Standard
we will inform at an early stage about inevitable product discontinuance. According to this we cannot guarantee that all
products within our product range will always be available. Therefore it needs to be verified with the field sales engineer or
the internal sales person in charge about the current product availability expectancy before or when the product for
application design-in disposal is considered. The approach named above does not apply in the case of individual
agreements deviating from the foregoing for customer-specific products.
