Overview
The TMI7321 is an integrated IEEE 802.3af PoE compliant Powered Device (PD) power supply solution. It includes a PD interface and an isolated/non-isolated fly-back or Buck converter. The PD interface includes detection and all the functions of IEEE 802.3af, classification, 150mA inrush current, 450mA operation current limit as well as 100V Hot-swap MOSFET. The DC/DC converter uses fixed peak current and variable frequency discontinuous conduction mode (DCM) to regulate constant output voltage. The primary-side regulation without opto-coupler feedback in fly-back mode simplifies the design while buck mode continues minimizes the solution size for non-isolated applications. A 160V integrated power MOSFET optimizes the device for various wide voltage applications It incorporates over current, open-circuit, and overvoltage protection and thermal shutdown. The TMI7321 supports a front-end solution for PoE-PD application with minimal external components and is available in QFN4x5-28 package.
