The device delivers up to 16A of load current "* and regulates the output voltage over load, line, and temperature ranges. 5)(&"1 Optional spread-spectrum frequency modulation minimizes radiated electromagnetic emissions due to the switching frequency. The I2C programmable I/O (SYNC) enables #(4 system synchronization.

The device is offered with a factory-preset output voltage that is dynamically adjustable (%&' through the |2C interface.

Overtemperature Protection Thermal overload protection limits the total power dissipation in the MAX20011C/MAX20011D. When the junction temperature exceeds +165°C (typ), an internal thermal sensor shuts down the internal bias regulator and the step-down controller, allowing the IC to cool. The thermal sensor turns on the IC again after the junction temperature cools by +15°C. ~~��� ��� � � � � � � � � � � � � � � � �~~ $��

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
