Abstract
An embodiment of the invention relates to a power converter including a resistor divider with an internal node to sense an input line voltage. The internal node is operable as a multifunctional pin. A controller compares a feedback voltage dependent on a power converter output characteristic to a current-sense signal including an offset dependent on a voltage of the internal node to control entry and exit of the power converter from burst mode operation. The node may be employed to manage power converter operation by sensing or controlling its voltage to signal operation in a standby or burst mode, to sense the input line voltage, to enable an external system to signal shutdown to the power converter, and to enable the power converter to signal a delayed restart condition to the external system.
