Product Overview

The TPS23754PWP is a high-power/high-efficiency PoE Interface and DC to DC Controller support a number of input voltage ORing options including highest voltage, external adapter preference and PoE preference. These features allow the designer to determine which power source will carry the load under all conditions. The PoE interface features the new extended hardware classification necessary for compatibility with high-power midspan power sourcing equipment (PSE) per IEEE 802.3at. The detection signature pin can also be used to force power from the PoE source off. Classification can be programmed to any of the defined types with a single resistor. The DC-DC controller features two complementary gate drivers with programmable dead time. This simplifies the design of active-clamp forward converters or optimized gate drive for highly-efficient flyback topologies. The second gate driver may be disabled if desired for single MOSFET topologies.
  • Supports high-efficiency topologies
  • Adapter ORing support
  • Programmable frequency with synchronization
  • Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
