MYBSP0122BABFT
Overview
The MYBSP0122BABFT is a surface-mount, isolated Power over Ethernet (PoE) DC-DC converter module designed for IEEE 802.3at Class 4 compliant devices. It provides a regulated 12V output at up to 2.125A (25.5W) from a standard PoE input range of 37V to 57V. This module simplifies the design of networked equipment by integrating the PD controller, isolation transformer, and power conversion into a compact 7-SMD package.
Why Choose This Part
The module offers a high efficiency of 92.5%, reducing thermal management requirements in enclosed housings. It features built-in self-protection including input undervoltage lockout and a hiccup-mode autorestart for output current limiting. The inclusion of a Type 2 PSE indicator signal simplifies the implementation of the IEEE 802.3at handshake for high-power operation.
Applications
Key Specifications
Getting Started
To integrate this module, ensure the PCB layout accommodates the 7-SMD module footprint and provides sufficient copper for thermal dissipation. Engineers should verify the Type 2 PSE Indicator pin logic to signal the system processor when full 802.3at power is available. Refer to the Murata application notes for recommended external input filtering to meet EMI compliance standards.
