MP8017GL-Z

Overview

The MP8017GL-Z is a Powered Device (PD) power switch IC compliant with the IEEE 802.3af standard for Power over Ethernet applications. It integrates an active clamp flyback converter capable of primary or secondary side regulation. The device operates within a supply voltage range of 0 V to 57 V and supports a maximum current limit of 1.5 A. It features a maximum duty cycle of 75% and functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a QFN-19 surface-mount package.

Feature Summary

• Compliant with IEEE 802.3af standards for PoE powered devices
• Integrates active clamp flyback converter with primary or secondary side regulation options
• Supports wide input voltage operation up to 57 V

Applications

• IEEE 802.3af compatible PoE powered devices
• LAN interface power management solutions

Procurement Notes

Verify the specific datasheet version and RoHS compliance status before finalizing procurement decisions. Confirm that the QFN-19 package dimensions align with your PCB footprint requirements. Ensure the operating environment remains within the specified -40°C to +125°C thermal limits to maintain device reliability and performance integrity.

Selection Notes

Select this component when designing systems requiring strict adherence to IEEE 802.3af specifications. The integrated active clamp flyback topology simplifies design complexity by reducing external component count. Consider the 1.5 A current limit and 57 V maximum input voltage when sizing downstream circuitry and ensuring adequate thermal dissipation for the QFN-19 package.
