Description

The EVL8030-QJ-01A is an evaluation board designed to demonstrate the capabilities of the MP8030, a fully integrated, IEEE 802.3af/at/btcompatible,Power over Ethernet(PoE),powered device (PD) with a PD interface and a high-efficiency forward controller.The PD interface has all the functions of IEEE 802.3af/at/bt. It integrates a 100V hot-swap MOSFET and a gate driver (GATE1) to improve efficiency for high-powered applications. The second gate driver (GATE2) supports an external, low RDS(ON) N-channel MOSFET to reduce high-power loss while the controller is powered from via adapter.The controller is designed for both primary-side regulation (PSR) in flyback applications and secondary-side regulation (SSR) in active clamped forward applications.It is recommended to read the MP8030 datasheet prior to making any changes to the EVL8030-QJ-01A.

Features

  • Compliant with 802.3af/at/bt Specifications
  • Internal Hot-Swap MOSFET for ≤51W Designs
  • External FET with GATE1 for >51W Designs
  • GATE2 N-Channel MOSFET Driver for Adapter Supply
  • Supports Automatic Classification
  • Automatic Maintain Power Signature Function
  • Primary-Side Regulation (PSR) for Flyback Applications
  • Secondary-Side Regulation (SSR) for Flyback Applications
  • SSR for Active-Clamp Forward Applications
  • Frequency Dithering for Reduced EMI
  • Ethernet Alliance (EA Gen 2) Certified
  • Available in a QFN-32 (5mmx6mm) Package

Typical applications

  • IEEE 802.3af/at/bt-Compliant Devices, Security Cameras, Video and VoIP Phones, WLAN Access Points, Internet of Things (IoT) Devices, Pico Base Stations
