A smart switch system comprising one or more switching devices. Each one of the switching devices include a first pin, a second pin, a current indication pin, a system current limit pin and a power switch for electrically coupling the first pin to the second pin when the power switch is turned on. Each switching device may adaptively adjust an operation current limit value of the switching device based on a system total current limit value received or set at the system current limit pin and a system current indication signal received at the current indication pin.

Smart switch system

A switching converter with adaptive constant on-time control has a power switch and a control circuit. The switching converter converts an input voltage into an output voltage. When the switching converter is in a light-load state, the on-time of the power switch is controlled to be smaller than the on-time of the power switch in a normal-load state, wherein the normal-load state includes a continuous current mode (CCM) or a discontinuous current mode (DCM).

Switching converters with adaptive constant on-time control and control methods thereof

A current balance circuit for a power management device having a first current channel and a second current channel, having: a first current sense circuit configured to detect a current flowing through the first current channel, and to provide a first current sense signal indicative of the current flowing through the first current channel; wherein the current balance circuit draws current from the second current channel to the first current channel based on the first current sense signal.
