PD70200ILD-TR Integrated Circuits (ICs)

PMIC - Power Over Ethernet (PoE) Controllers

Power over Ethernet (PoE) Controllers are used to power digital Ethernet devices. This can allow for a much larger network of devices without the need to install lots of wires or power outlets at different locations. The PD70200ILD-TR is a type of Power over Ethernet (PoE) Controller which helps to regulate the power and reduce unnecessary power loss. In this article, we will delve into the application field and working principle of the PD70200ILD-TR.

What is PD70200ILD-TR?

The PD70200ILD-TR is a Power over Ethernet (PoE) Controller IC used to provide instant power to digital Ethernet devices. It is based on the VSC8482T, a field-programmable analog IC. This means that the PD70200ILD-TR can be programmed according to the customer’s needs and requirements. The VSC8482T is a 4-channel programmable power supply controller which helps to regulate the power of the PD70200ILD-TR and provide up to 28 watts of power output.

Application Field

The PD70200ILD-TR can be used in a variety of applications. For example, it is commonly used as a PoE controller for IP cameras, VoIP phones, wireless access points and industrial instrumentation. It is also widely adopted in the medical field, such as wireless monitors, medical imaging system and even biometric fingerprint scanners.

Working Principle

The PD70200ILD-TR is based on power over Ethernet (PoE) technology. This technology allows it to supply power to digital Ethernet devices over a single Ethernet cable, eliminating the need to install multiple power outlets and cables. When an Ethernet device is connected to an Ethernet port, the PD70200ILD-TR will detect the device, detect its power requirements and then convert the available power source into the right power level, as specified in the 802.3af/at PoE standard.

The PD70200ILD-TR works by using a step-down DC to DC converter (a buck converter) to control the power supply. This allows it to regulate the voltage and current outputs, thus ensuring that there is no overtcurrent, or excessive power loss in the system. The PD70200ILD-TR also has an Over Current Protection (OCP) switch which will disconnect the power supply to the device if an over current is detected. This helps to protect the device from damage caused by sudden high current surges.

Conclusion

The PD70200ILD-TR is a type of Power over Ethernet (PoE) Controller which helps to regulate the power and reduce unnecessary power loss. It can be used in a variety of applications such as IP cameras, VoIP phones, industrial instrumentations and medical equipment. The PD70200ILD-TR works by using a step-down DC to DC converter to control the power supply, which helps to regulate the voltage and current outputs and also protect the system from power loss or damage caused by sudden high current surges.
