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) Under light load conditions the devices may not meet all specifications
(6) 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.

CIRCUIT DESCRIPTION
The MagI³C Power Module 173010x42 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.

LIGHT LOAD OPERATION
At light load conditions, the device skips switching cycles in order to keep the output voltage regulated as well as to increase the
efficiency under this condition.
SOFT-START
In order to prevent the output voltage from overshooting during start-up, a soft-start is implemented. The soft-start is internally set
and lasts around 1.3ms for both the 173010342 and 173010542. The figure below shows a start-up example, in this case with
173010342.

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 150°C (typ.), causing the device to enter a low power
standby state. In this state the MOSFET remains off causing V OUT to fall. Thermal protection helps to prevent catastrophic failures
from accidental device overheating. When the junction temperature falls back below 150°C (hysteresis is implemented) V OUT rises
smoothly and normal operation resumes.
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. When the 173010x42 recovers from a short circuit condition,
the soft-start is not active. Therefore, an overshoot at output voltage can be observed (see figure below).
Under short circuit condition the input current is limited to IIN,short (typ. 65mA)

For protection against load faults, the 173010x42 incorporates cycle-by-cycle current monitoring. During an overcurrent condition
the output current is limited and the output voltage drops. When the overcurrent condition is removed, the output voltage returns to
the nominal voltage.

It is important to be aware that in this configuration the 173010x42 must withstand the sum of the input voltage and the absolute
value of the output voltage (VIN + |VOUT|), instead of just the input voltage. This means that the maximum operating voltage should be
limited to 42V - |VOUT| (e.g. if the 171010542 is used in this configuration, the input voltage should not exceed 37V).
Moreover, the maximum output current of this configuration is no longer 1A, instead it must be reduced according to the below
mentioned formula (see also the graph below):
IOUT− = (1 − D) ∙ 1A

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.
