Abstract

An apparatus for delivering power to a load, which comprises a power converter that converts input power at a primary side to an output power and to a supply voltage to a secondary side. On the secondary side, a load switch is located on a current path to the load. A secondary-side control circuitry controls the load switch to operate in an ON mode in which current is provided to the load, and in response to a fault condition corresponding a voltage drop across the load switch exceeding a threshold value, activates circuitry on the secondary side. The circuitry, in response to the fault condition, causes the primary-side control circuitry to limit an extent to which the power converter is capable of supplying power.
