Miniaturised Surface Mount 24W Power-over-Ethernet Module

Overview

TopologyLAN / POE
Input voltage60 V
IC revision1.2

Description

The Ag5700-LPB series Power-over-Ethernet (PoE+) modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE802.3 PoE standard, with full backwards compatibility with the IEEE802.3bt, IEEE802.3at and IEEE802.3af amendments.The Ag5700-LPB is pre-configured as a Type 2 Class 4 device, allowing the module to draw up to 30W of power from the PSE, with nominal output voltages of 12V or 24V. The high efficiency DC/DC converter can achieve up to 89% efficiency and operates over a wide input voltage range with a low ripple and low noise output. The DC/DC converter also has built-in output overload, output short-circuit and over temperature protection and provides a 1500Vdc (input to output) isolation barrier.

Features

  • 24W continuous output power, 30W peak output power (IEEE802.3at)
  • 89% efficient DC/DC converter
  • 12V and 24V variants available
  • Low output ripple & noise
  • Overload, short-circuit and thermal protection
  • Adjustable output voltage
  • Industrial temperature range
  • Minimal external components required
  • Class 4 IEEE802.3 PD
  • IEEE802.3bt, IEEE802.3at, IEEE802.3af compliant
  • Small Surface mount (SMT) package size
  • 1500Vdc isolation (input to output)
  • Silvertel “design-in” assistance
