NOTES
(1) Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed
through correlation using Statistical Quality Control (SQC) methods.
(2) Typical numbers are valid at 25°C ambient temperature and represent statistically the utmost probability assuming the
Gaussian distribution.
(3) Depending on load current, see derating diagram
(4) Measured without heatsink, no air flow
(5) The industry standard for comparison of the output voltage ripple between switching regulators or modules requires a
10µF ceramic (sometimes additional 1µF ceramic in parallel) at the point of load where the voltage measurement is
done using an oscilloscope with its probe and probe jack for low voltage/high frequency (low impedance) measurement.
The oscilloscopes bandwidth is limited at 20MHz.

FDSM – Fixed Step Down Regulator Module
BLOCK DIAGRAM
CIRCUIT DESCRIPTION
The MagI³C Power Module 173xxxx78 is based on a non-synchronous step-down regulator with integrated MOSFET, free-
wheeling diode, power inductor, input and output capacitors. The control scheme is based on a Current Mode (CM)
regulation loop.
The VOUT of the regulator is divided with the internal feedback resistor network and fed into the error amplifier which
compares this signal with the internal 0.8V reference. The error signal is amplified and controls the on-time of a fixed
frequency pulse width generator. This signal drives the power MOSFET.
The Current Mode architecture features a constant frequency during load steps. Only the on-time is modulated. It is
internally compensated and stable with low ESR output capacitors and requires no external compensation network.

PROTECTIVE FEATURES
Over temperature protection (OTP)
The junction temperature of the MagI³C Power Module should not be allowed to exceed its maximum ratings. Thermal
protection is implemented by an internal Thermal Shutdown circuit which activates at 165°C (typ.), causing the device to
enter a low power standby state. In this state the MOSFET remains off causing VOUT to fall. Thermal protection helps to
prevent catastrophic failures from accidental device overheating. When the junction temperature falls back below 165° VOUT
rises smoothly and normal operation resumes.
Over current protection (OCP)
For protection against load faults, the MagI³C Power Module incorporates cycle-by-cycle current monitoring. During an
overcurrent condition the output current is limited and the output voltage is reduced. When the overcurrent condition is
removed, the output voltage returns to the nominal voltage.
Output overvoltage protection (OVP)
When the output voltage goes above approx. 109% of the specified output voltage the high side MOSFET will be forced off
until the output voltage falls below approx. 107% of specified output value.
Short circuit protection (SCP)
The short circuit protection is realized via cycle by cycle current monitoring. Recovery from short circuit protection mode
occurs during the switching cycle following the removal of the short circuit condition.

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
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.
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
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.
3. Best 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
