Various Circuits for Driving EN

DC-DC converter with isolation 72V to 12V various circuits for driving the EN

Input Undervoltage Protection: The converter will shut down after the input voltage drops below the under voltage protection threshold for shutdown. The converter will start to work again after the input voltage reaches the input under voltage protection threshold for startup.

Output Overcurrent Protection: The converter equipped with current limiting circuitry can provide protection from an output overload or short circuit condition. If the output current exceeds the output overcurrent protection set point, the converter enters hiccup mode. When the fault condition is removed, the converter will automatically restart.

FAQ

Q1: What is the purpose of a DC-DC converter with isolation?

DC-DC converters with isolations are widely used in scenarios that require electrical isolation, signal protection, and system safety, such as medical equipment, power systems, industrial control, communication equipment, and new energy vehicles, to achieve safe power transmission between different potentials and prevent noise interference and ground loop current problems.

Q2: How to use a DC-DC converter with isolation?

When using DC-DC converter with isolation, the user needs to select the appropriate input and output voltage and power level according to the system requirements, ensure that the input and output grounds are isolated from each other, correctly connect the pins or terminals, install it in a well-ventilated environment that complies with the electromagnetic compatibility design, and avoid working beyond the rated voltage and current range. At the same time, pay attention to the use of fuses or external protection circuits to improve the safety and reliability of the overall system.
