The LM5072MH-80/NOPB is an integrated Power Over Ethernet (PoE) Powered Device (PD) interface and PWM controller designed for IEEE 802.3af compliance. It supports a supply voltage range of 9V to 70V with a maximum power output of 12.95W. The device features internal switches and operates within a temperature range of -40°C to 125°C. Packaged in a 16-PowerTSSOP (16-HTSSOP) surface-mount case, it draws a maximum supply current of 2mA.
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package marking and datasheet revision levels match the specific order requirements. Check for obsolescence status as this component may be discontinued or superseded by newer revisions. Ensure storage conditions comply with moisture sensitivity level specifications prior to assembly.
Select this component for applications requiring strict adherence to IEEE 802.3af PoE standards with integrated control capabilities. Consider the 16-pin PowerTSSOP package for space-constrained surface-mount designs. Evaluate the 12.95W power limit against load requirements. Verify compatibility with existing DC/DC topology if auxiliary power is utilized alongside main data lines.
Manufactured by Texas Instruments, originally under National Semiconductor, this part belongs to the LM507x family of PoE controllers. It serves as a complete solution for integrating power delivery over Ethernet cables into electronic systems. The device simplifies design by combining interface logic and power conversion control in a single IC, reducing external component count compared to discrete solutions.
LM5073MH/NOPB is a related variant with a 14-pin HTSSOP package. LM5072MHX-80/NOPB offers tape-and-reel packaging options. Verify pinout and thermal performance differences when substituting.
