Design considerations
System capability must include ‘soft-start’ procedures, resilience to short-circuits, together with optimized thermal management and power density.
Superior protection and performance, such as low RDS(on) parameters, can be achieved by using dedicated PoE MOSFETs. They are designed specifically for the latest high-power PSE controllers.
