DC to DC converters have become the go-to solution for many applications requiring regulated output voltage and current ranging from a few milliwatts to kilowatts. Among the different types of DC to DC converters, the JCE0348S3V3-H belongs to the Buck Step-Down Converter family. It draws heavy voltage from an input source and then efficiently converts it to a lower voltage, generating very low ripple with constant current and voltage output over a wide operating temperature range.

The JCE0348S3V3-H provides up to 3W of continuous output power, making it suitable for a wide range of applications. It offers regulated output voltage of 3.3V with ± 5% accuracy and peak load performance up to 6W. The wide input voltage range (3V-20V) makes JCE0348S3V3-H ideal for battery-powered and secondary distributed power systems. The JCE0348S3V3-H operates in an e-coated metal case with an industrial grade pin-through-hole package, offering improved thermal performance and reliability.

The JCE0348S3V3-H operates on a fixed switching frequency of 500 kHz. This DC-DC converter is designed with synchronous rectification, enabling high efficiency up to 95% and improved thermal performance. It also contains an integrated 5V/0.2A startup regulator to provide soft start and inrush current limiting. It is also capable of shedding output power in response to an external signal, making it suitable for applications where power conservation is necessary.

The JCE0348S3V3-H is inherently no-load operation compliant and operates in a wide temperature range of -40°C to 125°C. It is fully protected against over temperature, over current, and over voltage, making it suitable for long-term, reliable operation in the most extreme environments.
