Overview
| Topology | LAN / POE |
| Output 1 | 12 V |
| IC revision | 1.1 |
Description
There is a common misconception regarding the power available to a device with Power over Ethernet (PoE) over the advertised power available for each standard. This application note is created as a guide to help understand the power available, and where power can be lost in a PoE application, in order to assist in adhering to the correct power limits when implementing a Silvertel module into an application such that (classification) power limits are not being exceeded.
Features
Very high efficiency (>93%)Environmentally friendlySIL - 57mm(L)x18mm(W)x14mm(H)Very low heat outputLow output ripple & noiseOverload, short-circuit and thermal protectionAdjustable output voltageVery few external low cost components requiredIndustrial temperature rangeClass 4 IEEE802.3 PDIEEE802.3bt, IEEE802.3at, IEEE802.3af compliant1500Vdc isolation (input to output)
Typical applications
- PoE
