Adaptive minimum on time control for a switching regulator

Adaptive minimum on time control for a switching regulator

A switching regulator includes a high side transistor coupled to an input voltage node. The switching regulator also includes a low side transistor coupled to the high side transistor at a switch node. An adaptive on-time control circuit is also included and is configured to cause the high side tran...

description A switching regulator includes a high side transistor coupled to an input voltage node. The switching regulator also includes a low side transistor coupled to the high side transistor at a switch node. An adaptive on-time control circuit is also included and is configured to cause the high side transistor to turn on for an adaptive period of time based on a ratio of an output voltage from the switching regulator to input voltage. The adaptive period of time is configured to occur responsive to a current through an inductor falling below a predetermined threshold.
