Murata has developed the MYBSP series of miniature surface-mount isolated DC-DC converters for Power over Ethernet (PoE).
This product can be used as a power converter for network devices including wireless access points, network security cameras, and IP telephones.
Mass production will be carried out by commencing in March 2017. The sample price is 4,000 yen.
In the network device market, an increasing number of devices are fitted with PoE for eliminating the necessity of installing AC power supplies and reducing wiring. Additionally, miniaturization of the power supply section of these devices along with the increasing degree of miniaturization and functional sophistication of equipment is necessary.
This newly developed MYBSP series of DC-DC converters incorporates hardware classification protocol functions that conform to the IEEE802.3at PoE communication standard. The product employs a sheet-type transformer, realizing high dielectric strength and reliability as well as miniaturization.
Until now, insertion terminal type power supply modules have been produced, but they necessitated mounting space on both sides of the customer’s board. The MYBSP product uses surface-mount cylindrical terminals, thus eliminating through-holes in the customer’s board and also enabling miniaturization of the power supply module itself. As a result, the area occupied by the board is reduced, increasing the degree of circuit design flexibility.
