MagI3C Power Module
FDSM - Fixed Step Down Regulator Module
28V / 0.5A / 3.3V and 5V Output
DESCRIPTION
FEATURES
The FDSM series of the MagI3C power module family is
a fixed output voltage, fully integrated dc/dc power sup-
ply. The module integrates the switching power stage,
control circuitry and inductor all in one package.
• Peak efficiency up to 95%
• 6V to 28V input voltage range
• 3.3V or 5V fixed output voltage
• 500mA output current
• Low output voltage ripple (typ. 10mV)
• Short circuit protection
The module requires no external components for ope-
ration. Input and output capacitors are integrated. De-
sign effort and complexity is reduced to a minimum.
• -40°C to 85°C ambient operating temperature
range
The FDSM ensures fast time to market and low deve-
lopment costs.
• Thermal shutdown
• Integrated capacitors and inductor
• Pulse skipping for high efficiency at light loads
• Fixed 570 kHz switching frequency
• Output overvoltage protection
• RoHS & REACH compliant
• UL94V-0 package material
It is pin compatible with the common 78xx linear re-
gulator series. The high efficiency reduces the power
dissipation and in many cases heatsinks and assembly
parts are no longer necessary.
Typical 12V to 3.3V conversion achieves 85% efficien-
cy. 12V to 5V conversion achieves 92 %.
The standard THT package allows for easy assembly.
TYPICAL APPLICATIONS
• Point-of-Load from 18V, 15V, 12V, 9V rail
• Replacement for linear regulators
• Interface and microcontroller supply
• General purpose

PROTECTIVE FEATURES
Overvoltage transient protection
This protection mode minimizes the occurance of output voltage overshooting. Once the output voltage reaches
an overvoltage threshold the switching from Vin will be stopped immediately via the high side FET. When the
output voltage falls below the overvoltage trip the high side FET will be enabled again.
Thermal shutdown
When the junction temperature exceeds a specific value the device stops switching until the junction tempera-
ture falls below this value.
Cycle by cycle current limiting
When the current through the high-side FET exceeds the current limit stated in the electrical specification the
high side FET will stop the current flow until the following cycle.
Short circuit protection
The short circuit protection is realized via the cycle by cycle current limiting. The short circuit protection is indefi-
nite with a recovery at the following switching cycle if the short circuit is removed.

IMPORTANT NOTES
The following conditions apply to all goods within the product range of Würth Elektronik eiSos GmbH & Co. KG:
1. General Customer Responsibility
Some goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain statements regarding general suita-
bility 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 and investigate, where appropri-
ate, 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.
2. 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 applica-
tions in which the malfunction or failure of an electronic component could endanger human life or health it must be ensured by
advanced technological aid of suitable design for the customer application that no injury or damage is caused to third parties
in the event of malfunction or failure of an electronic component.
3. Optimal Care and Attention
Any product-specific notes, warnings and cautions must be strictly observed.
4. 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 engi-
neer or the internal sales person in charge should be contacted who will provide support in this matter.
5. Product Reasearch & Development
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.
6. Product Life Cycle
Due to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of pro-
ducts. 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.
7. Property Rights
All the rights for contractual products produced by Würth Elektronik eiSos GmbH & Co. KG on the basis of ideas, development
contracts as well as models or templates that are subject to copyright, patent or commercial protection supplied to the cus-
tomer will remain with Würth Elektronik eiSos GmbH & Co. KG. Würth Elektronik eiSos GmbH & Co. KG does not warrant or
represent that any license, either expressed or implied, is granted under any patent right, copyright, mask work right, or other
intellectual property right relating to any combination, application, or process in which Würth Elektronik eiSos GmbH & Co. KG
components or services are used.
