Overview
The HPA01124PWPR is a high-power, high-efficiency Power over Ethernet (PoE) interface and DC/DC controller manufactured by Texas Instruments. Designed for IEEE 802.3at compliance, this component integrates PoE interface functions with a DC/DC controller to streamline power delivery in networked devices. It operates within an extended temperature range of -40°C to +125°C and is housed in a 20-pin HTSSOP package.
Feature Summary
- Integrates PoE interface and DC/DC controller functions for simplified system design
- Compliant with IEEE 802.3at standards for high-power Ethernet applications
- Optimized for high efficiency in power conversion processes
Applications
- IEEE 802.3at compliant powered devices
- High-efficiency PoE interface implementations
- Network infrastructure equipment requiring integrated power management
Procurement Notes
Verify the specific datasheet version and revision history before integration, as TI may update pinout definitions or electrical characteristics across manufacturing lots. Confirm that the HTSSOP-20 package thermal performance meets your PCB layout requirements for the intended operating temperature range of -40°C to +125°C. Ensure compatibility with your target IEEE 802.3at implementation standards.
Selection Notes
Select this component when designing systems requiring a single-chip solution for both PoE interface logic and downstream DC/DC regulation under IEEE 802.3at constraints. Consider the 20-HTSSOP package size relative to available board space. Evaluate thermal dissipation needs given the high-power capability and extended temperature range specifications compared to standard PoE controllers.
Part Context
This part belongs to Texas Instruments' portfolio of Power Over Ethernet controllers. It addresses the need for compact, efficient power delivery solutions in modern networking hardware. The integration of interface and control functions reduces component count and simplifies the bill of materials for certified PoE endpoints.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference data through official Texas Instruments channels or authorized distributor databases before considering alternative components.
