TPE15017-QF5R

AC DC Converters, Offline Switchers Overview

The TPE15017-QF5R is a highly integrated Power over Ethernet (PoE) Powered Device (PD) single chip from 3PEAK, compliant with the IEEE 802.3af standard. Designed for isolated PoE applications with power ratings below 13W, it combines PD detection, classification, and an active-clamp flyback power converter on one die. The device features a built-in 100V, 0.56Ω Hot-swap and Power MOSFET, eliminating external discrete components. It supports configurable Primary Side Regulation (PSR) or Secondary Side Regulation (SSR) modes and operates at switching frequencies up to 650kHz. Key technical attributes include Automatic Maintenance of Power Supply (MPS) functionality to maintain PSE connection under light loads, dual triangular wave frequency jittering for improved EMI performance, and compatibility with small EP7 transformers.

AC DC Converters, Offline Switchers Procurement Notes

Verify that the specific suffix -QF5R corresponds to the required tape-and-reel packaging format and temperature grade as defined in the official ordering information. Confirm that the component meets all relevant safety isolation requirements for the intended end-product design. Ensure the Bill of Materials includes compatible passive components suitable for the specified high-frequency operation.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs prioritizing minimal footprint and low cost in sub-13W PoE applications. The integrated MOSFET and support for PSR simplify the schematic by removing the need for optocouplers or secondary-side regulation circuits. Consider the QFN3X4 package constraints for thermal management and PCB layout. Verify transformer availability in EP7 packages to fully leverage the high-frequency capabilities.
