The detection signature pin Complete PoE Interface can also be used to force power from the PoE source off. Classification can be programmed to any of the Enhanced Classification per IEEE 802.3at With defined types with a single resistor. Status Flag The DC-DC controller features two complementary Adapter ORing Support gate drivers with programmable dead time. This Programmable Frequency With Synchronization simplifies the design of active-clamp forward Robust 100-V, 0.5- Hotswap MOSFET converters or optimized gate drive for highly-efficient 40C to 125C Junction Temperature Range flyback topologies. The second gate driver may be disabled if desired for single MOSFET topologies. Industry Standard PowerPAD HTSSOP-20 The controller also features internal soft start, bootstrap start-up source, current-mode 2 Applications compensation, and a 78% maximum duty cycle. A IEEE 802.3at Compliant Devices programmable and synchronizable oscillator allows design optimization for efficiency and eases use of Video and VoIP Telephones the controller to upgrade existing power supply RFID Readers designs. Accurate programmable blanking, with a Multiband Access Points default period, simplifies the usual current-sense filter design trade-offs.

The PoE interface supports the IEEE PART NUMBER PACKAGE BODY SIZE (NOM) 802.3at standard. TPS23754 The TPS23754 and TPS23756 support a number of TPS23754-1 HTSSOP (20) 6.50 mm 4.40 mm input voltage ORing options including highest voltage, TPS23756 external adapter preference, and PoE preference.
