Murata Manufacturing Co., Ltd. has expanded its lineup of isolated DC-DC converters for PoE with the launch of an IEEE802.3af-compliant isolated DC-DC converter for PD. Murata has already started mass production of the product, and samples are available upon request.
PoE technology enables power supply over LAN cables used to build networks, improving installation flexibility, and reducing costs. In recent years, network-enabled devices such as security cameras and biometric authentication equipment have increasingly adopted PoE technology. Against this backdrop, demand for compact power modules for PoE-compatible devices is growing. In particular, biometric authentication devices typically require around 10 W of power, making the IEEE802.3af standard, which supports up to 15 W, an ideal match.
Accordingly, Murata has developed this product compliant with IEEE802.3af. The product’s compact, low-profile design (1.02×0.58×0.27 inches (26×14.8×6.8mm)) enhances layout flexibility on circuit boards. It is mainly suited for camera modules and biometric authentication devices that require space-saving and low-noise characteristics, and contributes to the miniaturization of other communication devices.
Key features:
- Isolated DC-DC converter module compliant with IEEE802.3af Class specifications
- Compact and low-profile (1.02×0.58×0.27 inches (26×14.8×6.8mm)) for high layout flexibility
- Wide operating temperature range (-40°C to +85°C) for versatile applications
Applications:
IEEE802.3af-compliant devices including wireless access points, biometric authentication devices, security cameras, camera modules, IP phones, and audio speakers
Specifications:
- PoE: Power over Ethernet. A technology that enables power supply over LAN cables used to build networks.
- PD: Powered Device. A device that receives power in a PoE system.
