MPS MP8004GQW-Z

Контроллер (PD), DC/DC13 W802.3af (PoE)

Overview

MP8004GQW-Z Monolithic Power Systems, IC IEEE 802.3The MP8004GQW-Z is an integrated IEEE 802.3af PoE compliant Powered Device (PD) power supply solution. It includes a PD interface and an isolated/non-isolated flyback converter.The PD interface includes detection and classification modes as well as a 100V output pass device. Inrush current limit is included to slowly charge the input capacitor without interruption due to die heating.The DC-DC converter includes a 150V power switch and is capable of delivering 13W PoE power with high efficiency. It has an internal soft-start, auto-retry, and incorporates over current, short circuit, and over voltage protection. It can also skip cycles to maintain zero load regulation.The MP8004GQW-Z can support a front-end solution for PoE-PD application with minimum external components, and is available in thermally enhanced 4x6mm QFN20 package.Applications:• VoIP Telephones• Security Camera Systems• Wireless Access Points/Wireless LAN• Small-cell Base Stations• Safety Backup Power• Remote Internet Power Bostock Electronics is an authorized Monolithic Power Systems distributor.
