1. An apparatus comprising:
a transformer;
a primary-side controller coupled to the transformer;
a power factor correction (PFC) component coupled to the primary-side controller; and
a secondary-side controller coupled to the transformer, wherein the secondary-side controller is configured at least to:
obtain data informative of an amount of power;
determine whether the amount of power satisfies a power threshold condition; and
in response to determining that the amount of power satisfies the power threshold condition, cause the PFC component to operate in a PFC-disable mode by generating a PFC control signal that causes the primary-side controller to modulate a level of a PFC-disable signal.
