DC DC Converters

PH75F48-3 Application Field and Working Principle

The PH75F48-3 converter is a stepping down DC-DC module designed to reduce a high DC voltage to a comparatively lower DC voltage—commonly used in embedded applications. This converter can operate over a wide range of input voltage from 9V to 36V resulting efficient power conversion from the input to the output. Examples of its applications include smartphones, tablets, and various other audio/visual devices.

In terms of how the converter works, it takes the high input voltage, runs it through a filter (consisting of an inductor and capacitor) which removes any noise that could be generated by the power source, then converts it into a low output voltage. This is done through a process of switch control and energy storage. The switching control can either be done through either an analog PWM signal or a digital logic pulse, while the energy is stored in the inductor and capacitor of the filter.

The efficiency of the conversion is primarily determined by the quality of the circuit components used as well as the efficiency of the switching regulator. The PH75F48-3 module has a switching frequency of 500KHz, which is much higher than conventional regulators and makes it an efficient and fast converter. Its efficiency can range from 90%-95%, depending on the input voltage.

As a safety and protection mechanism, this converter module also comes integrated with an over-voltage protection (OVP) which ensures the converter doesn’t operate beyond the specified input voltage limit. Furthermore, it also includes an over-temperature protection (OTP) which shuts off the converter when it exceeds the temperature operating range of -40℃ to +85℃.

To recap, the PH75F48-3 converter is a DC-DC module, widely used in embedded systems, which reduces a high DC voltage to a comparatively lower DC voltage. It is highly efficient, comes with integrated safety and protection mechanisms and can operate over a wide input voltage range.
