Ag7200 Silvertel

V1.0 Nov 2017 Datasheet Ag7200 Silvertel 48V Boost Converter Module 1. Features PbPb Small SIL package Suitable for IEEE802.3af compliant PSEs Industrial Temperature High efficiency (>90%) Input voltage range 5V to 15V Minimal external components required Short-circuit and Thermal protection Adjustable Output (36V to 57V) 1500V isolation (input to output) Silvertel design-in assistance 2. Description The Ag7200 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 power and isolation requirements. The module accepts a wide DC voltage input range, from 5V to 15V. The input voltage is then boosted to generate the higher voltages required to power any IEEE802.3af PSE circuits (including those supplied by Silvertel). The Ag7200 provides a regulated adjustable output, of between 36V and 57V. Ag7200 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.
