MYBSP Isolated DC/DC Converters Murata MYBSP Isolated DC-DC Converters are ideal for devices compliant with IEEE 802.3bt or IEEE 802.3at. These converters offer an input range of 41.1VDC to 57VDC with a typical efficiency of up to 93.2% and 2250VDC input-output isolation. The modules come with self-protection features, including input undervoltage lockout and output current limit, using the hiccup auto-restart technique. Murata MYBSP Isolated DC-DC Converters are designed for Power over Ethernet (PoE) applications such as wireless access points, network security cameras, and IP telephones.
