Introduction

DC DC converters are used to convert direct current (DC) to direct current (DC) of a different voltage power. CDS4004807 is a DC DC converter that is widely used in various fields today. In this article, we will discuss the applications and principles of CDS4004807.

Applications of CDS4004807

CDS4004807 DC/DC converters are a kind of miniature, high-reliability, galvanic-isolation based power supplies. It has a wide range of applications which results from the fact that it can work on input and output voltage ranges from 3V to 24V, and with up to 35W of output power.The applications of CDS4004807 include driving television reception circuits, power supplies, high frequency telecommunication systems, power management, digital control systems, lighting systems, battery charge/discharge systems, power systems on board automobiles, instrumentation, and communication systems. Additionally, this DC/DC converter can be used to provide isolated power to microcontroller or processor voltage regulation system and support power supplies for PC or computer systems. CDS4004807 DC/DC converters are effective for operations which require low voltage and noise, such as in medical apparatus and industrial instruments. They can also be used to power LED display lighting systems and as emergency power supplies in telecommunication systems.

Working Principle of CDS4004807

The CDS4004807 DC/DC converter operates using a magnetic-type switch mode power supply technique known as “Iron Core Pulse Width Modulation (PWM)”. This method is again divided into two parts, namely primary side PWM and secondary side PWM. Primary Side PWM is a process where an output voltage of a DC/DC converter is regulated by intermittently closing an iron core in the primary side of the power transformer for predetermined intervals. Thus, the output voltage from the converter remains constant. Secondary Side PWM is a process of controlling the output voltage by adjusting the duty cycle of the PWM signals sent to the secondary side of the power transformer. It is done by controlling the take-off time of the the output voltage signal when the secondary side control circuit detects a variation in the output voltage. This ensures that the output voltage is relatively constant, even in the presence of load variations.Apart from these, the CDS4004807 DC/DC converter is also protected against over-current, over-voltage and thermal overloads, which helps maintain the stability and safety of the converter.

Conclusion

CDS4004807 DC/DC converters can be effectively used in applications where low voltage and noise is essential. These converters can be used in various applications ranging from automotive and medical equipment to emergency telecommunication systems and LED displays. The DC/DC converters are protected against over-current, over-voltage and thermal overloads to ensure the safety and stability of the converter. Furthermore, the working principle of CDS4004807 is based on Iron Core Pulse Width Modulation (PWM), which is further subdivided into primary side PWM and secondary side PWM. Thus, this article has provided a comprehensive overview of the applications and principles of CDS4004807 DC/DC converters.
