MEZD72402A-G application field and working principle of DC DC converters

MEZD72402A-G is high-performance, isolated DC/DC converters which belong to the broad category of DC/DC converters. It incorporates a wide input voltage range of 24 V – 320 V DC, and output power range of 0.2 W – 10 W. Due to its wide input voltage range, the MEZD72402A-G can be used as either a single-output power supply or a multi-output power supply, making it suitable for a variety of applications.MEZD72402A-G is an all-in-one converter that includes an integrated isolation transformer, voltage regulator, EMI filter, input rectifier, output rectifier, and other components. It has a low temperature coefficient and wide frequency range for high efficiency operation, while its integral EMI filter can meet EU EMC emission and immunity requirements. Its working principle is based on the fundamental concept of transformer-coupled regulation. In this arrangement, the input voltage is rectified and fed to the AC side of the isolation transformer, which transforms the voltage to the desired output voltage. The rectified voltage is then rectified again on the DC side, and applied to the primary of a voltage regulator circuit. Through careful control of the output voltage, the voltage regulator is able to provide near perfect regulation.The MEZD72402A-G also includes a frequency discriminator circuit to reduce the noise associated with switching. This frequency discriminator circuit monitors the input voltage and prevents the output voltage from being affected by frequency variations. The frequency discriminator also prevents over voltage and under voltage conditions, allowing the MEZD72402A-G to provide reliable voltage regulation in a variety of applications.In summary, MEZD72402A-G is a highly versatile, isolated DC/DC converter which features a wide input voltage range of 24 V – 320 V DC, and output power range of 0.2 W – 10 W. Its advanced circuitry ensures efficient, reliable voltage regulation, while its integrated isolation transformer and frequency discriminator reduce noise and ensure stable output voltage. MEZD72402A-G is an ideal choice for a variety of DC/DC conversion applications.
