IntroductionDC DC converters are power management products which convert electrical power from a power source with one set of Direct Current (DC) specifications to another set with different DC specifications. One such product is the REC7.5-483.3SRW/H1/A/M/SMD DC-DC converter, which provides either a regulated or unregulated DC output with specified input and output voltage requirements. The REC7.5-483.3SRW/H1/A/M/SMD is a high-efficiency, high-density DC-DC converter which features a non-isolated buck converter topology.Application FieldThe REC7.5-483.3SRW/H1/A/M/SMD is designed for use in a variety of applications, including high end computing, storage, telecommunications, and home appliances. The high efficiency and high power density of this DC-DC converter makes it suitable for applications where weight and thermal management are important. The REC7.5-483.3SRW/H1/A/M/SMD is designed to be used in applications where the input voltage range is 0.7V-5.5V and the output voltage can be selected to range from 0.7V-30V. This wide range of operation makes the REC7.5-483.3SRW/H1/A/M/SMD suitable for use in many consumer and industrial devices.Working PrincipleThe REC7.5-483.3SRW/H1/A/M/SMD is a non-isolated buck converter topology, meaning it uses a switching device to regulate the output voltage. The switching device is typically a power MOSFET or IGBT which is used to control the output voltage by chopping the input voltage. The input voltage is rectified and smoothed by an output capacitor, and then the switching device is used to shut off the current at times of low demand, allowing for a lower operating voltage. This process reduces the total losses and increases the efficiency of the power conversion. The output voltage regulation is typically achieved using either a resistor-capacitor (RC) voltage divider or a voltage feedback circuit.The REC7.5-483.3SRW/H1/A/M/SMD also features several protection mechanisms to protect itself from damage. The device is equipped with an under-voltage, over-voltage, over-current, and over-temperature protection. The under-voltage and over-voltage protection will shut down the device in the event that the input and/or output voltage is outside the specified range. The over-current protection will shut down the converter should the output current exceed the specified limit. The over-temperature protection will shut down the device if the internal temperature exceeds the specified limit.ConclusionThe REC7.5-483.3SRW/H1/A/M/SMD DC-DC converter is a high efficiency, high density device which is designed for use in a variety of applications. It is capable of producing either a regulated or unregulated output voltage, and features a wide input and output voltage range. The device also features multiple protection mechanisms to prevent damage to the device. Thus, the REC7.5-483.3SRW/H1/A/M/SMD is a ideal choice for applications where weight and thermal management are important and where precise voltage control is a must.
