Ag7100

V1.0 May 2015 Datasheet Ag7100 Silvertel 57V Boost Converter Module 1. Features PbPb Small package Suitable for IEEE802.3af and IEEE802.3at compliant PSEs Low cost High efficiency (>90%) Input voltage range 12V to 27V Minimal external components required Short-circuit and Thermal protection Adjustable Output (48V to 57V) 1500V isolation (input to output) Silvertel design-in assistance 2. Description The Ag7100 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 (>90%) while providing full compatibility with the IEEE 802.3af and 802.3at power and isolation requirements. The module accepts a wide DC voltage input range, from 12V to 27V. The input voltage is then boosted to generate the higher voltages required to power Silvertels PSE modules (or compatible PSE circuits). The Ag7100 provides a regulated adjustable output, of between 48V and 57V. This provides compatibility with both IEEE802.3af and the higher power POE+ 802.3at PSE standards. Ag7100 has been designed to provide an ideal solution for powering the Silvertel Ag6100 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.
