• VoIP
• IP Cameras
• Wireless Access Points (WAPs)

It is also suitable for applications such as network routers, network switches and portable electronics.

Benefits

The LM5070SDX-50 provides manufacturers with a high-performance PoE solution that is efficient, reliable and cost-effective. This device offers designers several benefits, including:

• Power budgeting capability
• PD detection
• Low component count
• Compact design
• Cost-effective

Working Principle

The LM5070SDX-50 is capable of providing up to 30 Watts of PoE power. It is based on a power budgeting architecture that ensures that the power needs of each PD connected in series or in parallel is met. This device uses a PD detection technique to determine the power requirements of each PD. The power budgeting algorithm and PD detection capabilities help to ensure that the device is used efficiently and reliably.

This device also offers protection against PD outages due to excessive current draw. When a PD requests more than the allowed mains current, the device will detect the issue and shut off that PD’s power supply. This ensures that there is a safe and efficient power supply to each PD.
