DC-DC converters play an important role in modern electronic systems. The PT7747C is a high-performance, low-noise, low-cost and wide operating temperature range converter that has been widely adopted for critical uses. In this article, we will discuss the application field of PT7747C and its working principle.

Application field of PT7747C

As a choice of DC-DC converters, the PT7747C has a wide range of applications. It is mainly used to convert 5V to 15V DC voltage, which makes it suitable for the most of the common input and target voltage requirements. This converter is ideal for many applications such as military, automotive, medical, industrial and embedded systems.

The PT7747C can also be used in applications that require switching from high voltage to low voltage. It can be used to reduce the voltage on a battery-powered device which allows for increased run time. It is also able to handle high current applications like motor control, instrumentation and computers.

The PT7747C is also one of the most reliable converters in the market and it is designed for harsh environments. It boasts a wide operating temperature range of -40°C to +85°C and can handle up to 10A of dynamic current. This converter also has a low EMI, making it suitable for applications that require low-noise operation.

Working principle of PT7747C

The PT777747C operates using a boost topology. This means that it uses an input voltage and a charge storage device (typically a capacitor or an inductor) to generate an output voltage that is higher than the input voltage. The boost topology works in the following way:

The input voltage is first applied to the charge storage device. As current increases in the device, the voltage across it builds, creating a higher voltage than the input voltage. This higher voltage is then applied to the output side of the converter as an unregulated, stepped-up DC voltage.

The output voltage is then regulated by the PT7747C\'s internal voltage regulation circuit. This circuit maintains the required output voltage by monitoring the output voltage and adjusting the device\'s output current if needed.

The PT7747C is a highly efficient converter, boasting 97.8% efficiency at full load. This makes it a great choice for applications that require low power consumption. In addition, this converter\'s low-noise operation makes it suitable for applications that require low-noise operation.

Conclusion

The PT7747C is a high performance, low noise, low cost and wide operating temperature range converter that has been widely adopted for critical uses. It is an ideal choice for many applications such as military, automotive, medical, industrial and embedded systems. Furthermore, its boost topology allows it to step-up the input voltage to a higher output voltage, while also providing outstanding efficiency and low-noise operation.
