Working Principle

The JTE0348S12-H DC-DC converter is a switching mode regulator that utilizes the high-frequency switch FET to convert a DC voltage, 36V, into a higher or lower DC voltage to meet a certain application requirement. The high-frequency switch FET in the converter is continually turned on and off at a high frequency, and the output voltage is adjusted by varying the duty cycle, or the ratio of the on time to the total period. To reduce switching losses, the switching frequency is kept as high as possible, and noise-suppression techniques are employed so that the output voltage is as stable as possible.

The JTE0348S12-H utilizes synchronous rectifier to convert 36V DC into 5V DC with extremely high efficiency. A synchronous rectifier uses two internal FETs to switch on and off the rectifier circuit depending on the state of the input waveform. The switching frequency of the FETs is determined by two frequency setting pins, allowing the user to fine tune the switching frequency according to the application and the load.

Conclusion

The JTE0348S12-H is a high-efficiency, high-reliability DC-DC converter designed for use in a variety of applications. This product utilizes synchronous rectifier technologies and high-frequency switching to convert 36V DC into 5V DC. With its industry standard footprint and total height of 8.0mm, the JTE0348S12-H DC-DC converter is an ideal solution for automotive, industrial, and communication system applications.
