The UCC2581D is a sophisticated integrated circuit (IC) component designed for managing and controlling power systems in applications such as power over Ethernet (PoE) systems. This IC provides an efficient and reliable solution for power sourcing equipment (PSE) and power devices (PD).
One of the key features of the UCC2581D is its ability to offer IEEE 802.3bt-compliant PoE applications. It supports up to 100W of power delivery for devices connected to an Ethernet network. This feature makes it ideal for powering high-power devices like IP cameras, wireless access points, and small-cell base stations.
The UCC2581D implements a flexible architecture that allows it to handle multiple power conversion topologies, integrating power factor correction (PFC) and DC-DC conversion to ensure highly efficient power delivery. This architecture ensures minimal power losses and reduces strain on the power supply, resulting in enhanced energy efficiency.
To accommodate different system requirements, the UCC2581D supports wide input voltage ranges, typically from 42V to 57V, and features programmable output voltages from 3V to 60V. This flexibility enables the IC to be used in various applications and environments.
The built-in comprehensive fault protection mechanisms are another vital aspect of the UCC2581D
