1. 2. Description

The DP7200 module is a low noise DC/DC boost converter, designed to generate the higher voltages required for IEEE802.3 PSE applications from lower voltage supplies. This module provides exceptional efficiency (>92%) while providing full compatibility with the IEEE 802.3af/at power and isolation requirements.

The module accepts a wide DC voltage input range, from 10V to 15V. The input voltage is then boosted to generate the higher voltages required to power any IEEE802.3af/at PSE circuits (including those supplied by Sdapo). The DP7200 provides a regulated adjustable output, of between 36V and 57V.

DP7200 has been designed to provide an ideal solution for powering the Sdapo DP6100 PSE module from a vehicle battery, 12V plug-top PSU or other commonly available power supplies. Its low cost, small footprint, high efficiency and in-built isolation make it an extremely versatile DC-DC boost converter for a wide range of potential applications.

2  Functional Description

2.1 Typical Connections

The DP7200 has a wide input voltage range of 10Vdc to 15Vdc; as shown in Figure 3.

Depending on the length of lead and decoupling of the power supply being used the

customer may need to connect an electrolytic capacitor across the Ag7200 input which will reduce the ripple from the supply.

2.2  Output Voltage Adjustment

The DP7200 series has an OADJ pin, which allows the output voltage to be increased or decreased.

 Figure 4 shows how the ADJ pin is connected.
