Abstract
A power over Ethernet (PoE) power sourcing equipment (PSE) architecture for variable maximum power delivery. PoE PSE subsystems rely on some control to 'turn on' a power field effect transistor (FET), which allows current to be transmitted to a powered device (PD). A hybrid approach is provided where an internal FET can be augmented with an external FET to provide an architecture that can be flexibly applied to applications with various space, cost and cooling limitations. The maximum delivered power can also be boosted with the addition of an external FET to the internal FET.
