As the power center of electronic products, the endurance of power supply directly determines the service life of electronic products. With the continuous progress of integrated circuit manufacturing process, the power supply voltage of digital circuits has been declining, but the power supply of the system is still at a high potential, so it is necessary to rely on the step-down power supply to provide a lower power supply.

When you use CAN or RS-485 bus for debugging, have you ever encountered occasional communication errors? Or the data cannot be received? A bus that has been in normal use suddenly has a wide range of errors, or the node is damaged? Are you still at a loss for these problems? Using bus isolation may help you solve the problem easily.

With the development of power technology, the control of high-frequency switching power supply has gradually developed from the original analog circuit to the highly integrated control devices such as microprocessors and DSP. These devices are small in size and high in precision, but the electromagnetic interference and radiation in the switching power supply are stronger than other communication equipment working environment, which puts forward higher requirements for the auxiliary power supply.
