NCP1080DER2G

Overview

The NCP1080DER2G is an integrated Power over Ethernet Powered Device (PoE-PD) and DC-DC converter controller manufactured by onsemi. Designed for applications requiring up to 13W of power, this component combines PoE interface logic with a high-performance switching controller. It operates within a wide input voltage range and supports various output configurations. The device is housed in a TSSOP-20 surface-mount package, facilitating compact PCB layouts for network infrastructure equipment.

Feature Summary

• Integrates PoE-PD interface logic with DC-DC conversion control
• Supports IEEE 802.3af compliant power delivery standards
• Includes built-in protection mechanisms for system reliability
• Optimized for low component count in power supply designs

Applications

• VoIP phones and wireless access points
• Network surveillance cameras and sensors
• Industrial IoT edge devices
• Smart building automation controllers

Procurement Notes

Verify the specific suffix DER2G against the official datasheet to confirm package type and tape-and-reel specifications. Check current lifecycle status as components may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring integrated PoE reception and isolated DC-DC conversion in a single IC. It is suitable for cost-sensitive applications where board space is limited. Consider the 13W power limit and input voltage range relative to the target application's power budget and network infrastructure capabilities.

Part Context
