Texas Instruments TPS23752PWP
- Part Number:
- TPS23752PWP
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3267458-TPS23752PWP
- Description:
- IEEE 802.3at PoE interface with flyback DC-DC controller and Sleep Mode Feature
- Datasheet:
- tps23752
Description
The TPS23751 is a 16-pin integrated circuit that combines a Power-over-Ethernet (PoE) powered device (PD) interface and a current-mode DC-DC controller optimized specifically for applications requiring high efficiency over a wide load range. The PoE interface implements type-2 hardware classification per IEEE 802.3at. It also includes an auxiliary power detect (APD) input and a disable function (DEN). A 0.5 Q, 100 V pass MOSFET minimizes heat dissipation and maximizes power utilization.
The DC-DC controller features internal soft-start, a bootstrap startup current source, current-mode control with slope compensation, blanking, and current limiting. Efficiency is enhanced at light loads by disabling synchronous rectification and entering variable frequency operation (VFO).
The TPS23752 is a 20-pin extended version of the TPS23751 with the addition of a Sleep Mode feature. Sleep Mode disables the converter to minimize power consumption while still generating the Maintain Power Signature (MPS) required by IEEE802.3at.
