DC - DC Converters

DC/DC converters are used to convert one type of direct current (DC) power into another form of power or voltage. They perform a variety of functions, including powering electronic circuits, protecting components from voltage spikes, controlling current flow, providing power conditioning and isolation, and providing voltage and/or current regulation. The RV-1205S DC/DC converter is an adjustable step-down converter designed for a variety of applications.

Applications

The RV-1205S is designed for use in a range of applications, including industrial, automotive, medical and aerospace. These applications make use of its low-profile pin and solider type, and its wide input voltage range. It can be used to provide 5V or 3.3V power from an input voltage of 9V to 24V. It also features a low current cutoff switch which can be used to protect components from excessive current. This makes it an ideal choice for applications that require a range of different voltage output levels.

Working Principle

At the heart of the RV-1205S DC/DC converter is a high frequency switching regulator that is used to generate an adjustable, constant voltage and current. It works by measuring the input voltage and then rapidly switching a power transistor to deliver a stepped down version of the incoming voltage. This is done by rapidly switching the transistor between its ON and OFF states, with the transistor in the OFF state for a longer portion of the cycle than when it is in the ON state. This creates a square wave waveform that is then filtered to create a smooth DC output voltage.The RV-1205S can also be used as an adjustable current limiter, thanks to its integrated current limit feature. This feature prevents the DC/DC converter from exceeding the predetermined maximum current limit. This can be useful for protecting components from a power surge or for regulating the current supplied to a load.

Conclusion

The RV-1205S is a versatile DC/DC converter ideal for a range of different commercial and industrial applications. It works by rapidly switching a power transistor between its ON and OFF states, and filtering the resulting square-wave to produce a smooth DC output voltage. It is also equipped with a low current cutoff switch designed to protect components from excessive current, and an adjustable current limiter to ensure that the current supplied to a load does not exceed a predetermined value.
