NCP1080DEG Description

Short technical summary and product information.

The NCP1080DEG from ON Semiconductor is a highly integrated solution for demanding Ethernet applications, combining a PoE-PD interface with a configurable DC-DC converter controller. This device fully supports the IEEE802.3af specification, enabling products to be powered directly over Ethernet lines and reducing the need for local power adaptors.

 

It offers a regulated power output of up to 13W, making it suitable for applications such as VoIP phones, wireless LAN access points, and security cameras. The integrated current mode DC-DC controller facilitates various converter topologies, including fly-back and forward, with features like programmable switching frequency and a duty cycle up to 80 percent.

 

The NCP1080DEG is fabricated in a robust high-voltage process and includes a rugged vertical N-channel DMOS pass-switch. It operates within an industrial temperature range of -40°C to 85°C and features over-temperature protection. The device is available in a 20-TSSOP package with an exposed pad, designed for surface mounting.

 

Key electrical specifications include an input voltage range of 0V to 57V and internal switches. It is designed to withstand harsh environments, including hot swap and cable ESD events.
