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 16):
A method of programming a switching converter, comprising:\n selecting a resistor having a value that corresponds to a valley switching point of a drain voltage of a power MOSFET; attaching the resistor to a gate terminal of the power MOSFET and to a voltage input pin of a controller in the switching converter to form a gate node; applying a voltage to an input pin of a controller in the switching converter; generating a first current through the drive pin via a switch and through the resistor; generating a second current having a same value as the first current through a compensation time selection circuit where the compensation time selection circuit transforms the second current into a digital value; correlating the digital value of the second current with a compensation time from a plurality of compensation times stored in the compensation time selection circuit; and programming the correlated compensation time in the controller, wherein the programmed 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 reaches the valley switching point during a switching cycle.
