Texas Instruments Power-over-Ethernet PD Controller 20-Pin HTSSOP

The Texas Instruments Power over Ethernet 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.

• DC to DC control optimized for isolated converters
• Supports high efficiency topologies
• Complete PoE interface
• Enhanced classification per IEEE 802.3at with status flag
• Programmable frequency with synchronization
• Industry standard PowerPAD HTSSOP 20
