MICROCHIP EV96C70A 55W Dual Output Converter from 36V-54V Input EVB
Introduction
This document provides the description and operating procedures for Microchip’s dual output 55V/30W and 5V/25W board from 36V–54V input EV96C70A. This board type is used for evaluating the performance of Microchip PoE systems and the Microchip PWM controller LX7309, which is an integral part of Microchip PoE PD controllers PD70201 and PD70211.
Microchip’s PD70201 and PD70211 devices are a part of a family of devices that support the IEEE® 802.3af, IEEE 802.3at, and HDBaseT standards PD interface.
The PD interface includes the following family of devices.

Microchip’s EV96C70A evaluation board provides designers with the environment needed for evaluating the performance and implementation of PoE PD applications.
The board uses two PWM LX7309, which are an integral part of Microchip PD controllers PD70201 and PD70211.
This document provides all necessary procedures and instructions to install and operate this board.
Figure 1. EV96C70A Block Diagram
The board can be powered through an input connector J6 by a lab supply or by an output of PoE PD front end. See section 1.3. Electrical Characteristics for the input voltage range. The external load is connected to the evaluation board using the J1 (5V/25W) and J7 (55V/30W) output connectors. The following figure shows the location of input and output connectors.
D5 is the 55V indication LED and D9 is the 5V indication LED. These LEDs indicate the presence of the corresponding outputs.
The following figure shows a top view of the evaluation board.
