DC DC Converters have been widely used in the industrial field as an essential component for power distribution and conversion. They are heavily utilized to convert power from various sources and to distribute it across various applications. The PT6702C is a type of DC-DC converter which is widely used in the industry for its optimal functional capabilities. This article aims to discuss the applicable field of PT6702C and its working principle.

Applicable Field of PT6702C

PT6702C is a type of DC/DC converter used for applications that require solid state power supplies. It is suitable for power supply designs with high efficiency, small no-load power consumption, low temperature rise, as well as high power density and wide output current range. It is also suitable for driving high speed switching devices, such as micros, DC brushless motors, and LED light sources.

It can also be used in various applications, such as industrial control systems, automatic control systems, digital broadcasting equipment, and computer power supply systems. The device is configured as a step-up DC/DC converter with a DC input voltage range of 1.5V to 5V. It can convert the input voltage into a stable output voltage range of 24V to 50V DC. It utilizes a wide variety of high-efficiency topologies that are able to work at frequencies up to 100kHz.

Working Principle of PT6702C

The working principle of PT6702C DC/DC converter is based on its internal control principle. It makes use of its power switches and inductor to switch the energy from the input voltage and transfers it to the output voltage. The power switches are configured to switch the energy between two distinct power sources. The power switches are then controlled by the internal control circuit which enables the converter to adjust the output voltage according to the input voltage. The internal controller manages the voltage transformation by controlling the on and off state of the power switches.

The step-up converter is configured as a buck converter, where the inductor is placed between the power switch and the output capacitor. The inductor stores the energy during the charging cycle and releases the stored energy during the discharging cycle. The inductor prevents the current from flowing back to the input, thus ensuring a continuous flow of energy from the input to the output.

In order for the power switch to create the required output, the output voltage is programmed by the feedback control circuitry. The feedback control circuit monitors the output voltage of the converter and regulates the conduction period of the power switches. The feedback control circuit is designed to maintain a certain amount of voltage differential between the input and output of the converter. The feedback control circuit is also responsible for controlling the overtemperature detection, short circuit and overload protection.

Conclusion

The PT6702C DC/DC converter is a reliable and efficient way of transforming low-voltage input power source into a high-voltage output. It is suitable for applications that require a step-up conversion of small input voltage to a higher output voltage. It features high-efficiency, low-noise, and a wide input and output voltage range. With its internal control circuit, the PT6702C is able to maintain the required input and output voltage and protect the device from overtemperature, short circuit, and overload.
