DC DC converters are electrical power conversion devices used to transfer power in either electronic or electrical systems. IB048Q096T64N1-00 is a medium power DC DC converter specifically designed for Power over Ethernet (PoE) applications, allowing the signal and power to co-exist. In this article, we will discuss its application fields and working principle.

Application field

IB048Q096T64N1-00 DC DC converter is ideal for PoE applications. PoE has made it possible to power an Ethernet device by using just one network cable for both power and data transmission. This converter supports the IEEE802.3 PoE standard and its ± 9V output voltage allows it to supply power up to 60W. It also features a Temperature-compensation circuitry and supports a working temperature range of -20°C to 80°C. These features make it suitable for powering Ethernet Cameras, Access Points, VoIP phones, thin clients, etc. Moreover, its protective circuitry allows it to protect the device from input over voltage, temperature, high voltage and overload.

Working Principle

The IB048Q096T64N1-00 DC DC converter is a DC to DC converter, which converts the input DC voltage into an output DC voltage with different characteristics. It is based on a switching network of components and works on the principle of resonant conversion. The converter includes a Buck or Boost inductor, capacitors, switches, and a controller along with other components adopting the charge pump topology. The switches connected to the monitoring circuitry are used for controlling the output voltage. The most commonly used switches are MOSFETs, which are used to modulate the input voltage and regulate the output voltage.

The inductor used in the converter stores the energy when the switches are closed, allowing the current to flow. The capacitor on the output side of the converter stores the energy when the switch is in off-state, acting as a buffer for the output voltage ripple. The converter also includes a controller to switch on/off the switches and maintain the output voltage.

In conclusion, the IB048Q096T64N1-00 DC DC converter is an ideal solution for powering PoE Ethernet devices due to its ±9V output voltage, protective circuitry, and temperature compensation features. Its working principle is based on a switch network and the charge pump topology.
