MCZ34670 IEEE 802.3af Powered Devices
- このページには、製造中止（生産終了）となった製品の情報が記載されています。本ページに記載されている仕様および情報は、過去の参考情報です。
The NXP® MC34670 combines a power interface port for IEEE 802.3af powered devices and a high performance current mode switching regulator. It allows you to build PDs with a minimum of external components by integrating the required IEEE 802.3af functions with all functions necessary to build a high efficiency DC/DC converter.
- Fully supports the IEEE802.3af standard and provides complete signature and power classification functions
- Controls inrush current limiting and incorporates adjustable undervoltage lockout
- The switching regulator provides excellent line and load regulation and drives an external power MOSFET with sense resistor
