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.
