Abstract:
A switching converter is provided that includes a power MOSFET, a controller having a drive pin connected to a gate terminal of the power MOSFET, and a resistor connected to the gate terminal. A compensation time selection circuit is included that has compensation times stored therein. A compensation time is selected from the compensation times based on a value of the resistor and stored in the controller. The selected compensation time compensates for an inherent delay in switching the power MOSFET to an ON state after the power MOSFET receives a signal to switch to the ON state to allow the power MOSFET to switch to the ON state when a drain voltage of the power MOSFET's reaches its lowest value during a switching cycle.

Claim (Index 9):
A switching converter, comprising:\n a power MOSFET having a gate terminal connected to a gate node; a compensation time programming circuit comprising:\n a drive pin of a controller, the drive pin connected to the gate node; \n a resistor connected to the gate node; \n a current source configured to supply a first current through the drive pin via a switch and through the resistor where a value of the current is based on a value of the resistor; and \n a compensation time selection circuit that converts a second current from the current source to a digital value, the compensation time selection circuit configured to store a plurality of compensation times; and \n wherein a compensation time is selected from the plurality of compensation times based on a value of the digital value of the second current, and \n wherein the selected compensation time compensates for a delay in switching the power MOSFET to an ON state after the power MOSFET receives a signal to switch to the ON state, so as to allow the power MOSFET to switch to the ON state when a drain voltage of the power MOSFET reaches a valley switching point during a switching cycle.
