摘要
In one implementation, a voltage converter includes a high side power switch, and first and second low side power switches. The voltage converter also includes a driver stage for driving the high side power switch and the first and second low side power switches, and an adaptive OFF-time control circuit coupled to the driver stage. The adaptive OFF-time control circuit is configured to sense a current through one of the first and second low side switches, and to determine an adaptive off time for the high side power switch based on the sensed current.
