Abstract: Described are computer implemented methods, a system and a power supply amplifier (PSA) that supports compliance testing of the PSA. The power supplies power to a powered device/information handling system. A voltage of synchronous rectifier (SR) gate is measured and compared to a calculated sense voltage at a sense resistor of the PSA. If the sense voltage is zero, received current of the PSA bypasses a first blocking MOSFET and a second blocking MOSFET for over voltage protection. If the sense voltage is not zero, the received current passes through the first blocking MOSFET.
