DC-DC converters are used in almost every type of power system. They can provide power from a single DC power source to multiple loads, or from multiple DC power sources to a single load. The PAH75S48-24/P is one of the most popular DC-DC converters. It is an isolated buck converter which makes it suitable for applications demanding electrical isolation between the input and the output.

Product Overview

The PAH75S48-24/P is a flexible, low-profile DC-DC converter capable of delivering up to 75W of continuous output power. It operates from a wide input voltage range of 9V-48V and can be used in a variety of applications. Its tight-voltage regulation and low ripple are also important advantages of the converter. The paH75S48-24/P features an EMI compliant design which provides improved reliability of power systems.

Application Field

The PAH75S48-24/P is designed for applications that require step-down capabilities from a wide input voltage range. Its wide input voltage range and ability to accept inputs as low as 9V make it an excellent choice for telecommunications, industrial, building automation, and other applications that require a reliable power source. The PAH75S48-24/P also features a wide output voltage range from 0.8V to 24V and can deliver up to 75W of continuous output power.

Working Principle

The PAH75S48-24/P works based on the buck converter principle. The converter takes the input voltage and reduces it to the desired output voltage. To do this, the converter uses an inductor to store energy while the switch is on and then releases it to the output when the switch is off. This process is repeated at high frequencies to maintain a steady output voltage.

The input voltage is supplied to the primary side of the transformer, where it is stepped down by a ratio determined by the turns ratio of the transformer. The voltage is then rectified and filtered by a pi-filter on the secondary side of the transformer. The output is then regulated using a feedback control circuit.

The PAH75S48-24/P also includes features which improve efficiency and reduce the size of the system. These features include an integrated soft-start circuit which helps reduce current surges during startup, as well as an adjustable switching frequency. This allows the user to select an optimal frequency for the application, improving system efficiency.

In addition, the PAH75S48-24/P is equipped with integrated current and thermal protection. These features provide an added layer of protection for the system, ensuring it is able to reliably operate in all applications.

Conclusion

The PAH75S48-24/P is a robust and reliable DC-DC converter designed to provide power from a wide range of input voltage sources. Its wide input voltage range and ability to accept input voltages as low as 9V make it suitable for various applications. Its small size and wide output voltage range make it a great choice for a variety of applications from the industrial sector to telecommunications.

The PAH75S48-24/P is designed to be easy to use and is equipped with features such as soft-start circuit, adjustable switching frequency, and integrated current and thermal protection. All of these features combined make the PAH75S48-24/P a great option for a DC-DC converter.
