PMP40355

Class 3 Non-isolated Floating Buck Converter for PoE PD Reference Design

PMP40355

Design files

Overview

The PMP40355 reference design is designed for evaluating a non-isolated 13W buck  PD converter system using the IEEE 802.3at PoE interface and dc/dc controller TPS23753A. The converter is capable of supporting the 13W maximum IEEE 802.3at power requirements with low BOM cost. It presents good efficiency, load regulation and related electrical performance.

Features
  • Compliant with IEEE 802.3at standard
  • Enhanced ESD ride-through capability
  • Combined PoE PD and DC-DC controller
  • Non-isolated configuration
  • Independent feedback path with temperature immunity
