TEXAS INSTRUMENTS TPS23756PWP 直流-直流开关稳压器, 可调, 0V-57V输入, 14.3V-15.7V输出, 253kHz, HTSSOP-20
The is a high-power/high-efficiency PoE Interface and DC-to-DC Controller optimized specifically for isolated converters. The PoE interface supports the IEEE 802.3at standard. The TPS23756 support a number of input voltage O-ring 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-to-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.
