PH75A28048

DC DC Converters

DC to DC converters are electronic components that are used to convert a DC voltage to a different DC voltage. The DC to DC converters are available in a large variety of shapes, sizes and features to suit any need. One such DC to DC converter is the PH75A28048, which is a high-efficiency, low-noise, compact DC to DC converter that maintains a small footprint. It has a wide range of input voltage and can provide up to 800mA output current.

The application field of the PH75A28048 includes applications that require a wide input voltage range from 3.2 to 40V, such as automotive, industrial, consumer, medical, and audio/video. It can be used in applications that require high stability and conversion efficiency while providing a low-noise operation.

Working Principle

The PH75A28048 DC to DC converter works by step-down voltage through a two-stage regulator topology. The first stage is a high-efficiency fixed-frequency flyback converter, which uses a goal of reducing the power losses. The second stage is a linear regulator, which is designed to further lower the output noise level and provide a small footprint. The two stages work together to reduce both ripple and EMI emissions.

The PH75A28048 includes a wide range of protection functions to ensure safe operation, such as over-voltage, undervoltage, and over-temperature protection. The converter also provides regulation accuracy of ±0.6%, and its feedback pins feature a +/- 5% trim range.

In conclusion, the PH75A28048 DC to DC converter is an efficient and reliable device, suitable for a wide range of applications. It provides high-efficiency and low-noise operation while maintaining a small footprint. It is also equipped with a wide range of protection functions, and its regulation accuracy and feedback pins feature a wide trim range.
