Abstract: A driver for driving a switched-mode power supply is presented. The driver receives a set of input signals. Each input signal is configured for changing a state of an associated power switch from a first state to a second state. The driver generates an output signal to change the state of the associated power switch from the first state to the second state. When the first state is an on state and the second state is an off state, the driver asserts the output signal to change the state of the associated power switch to perform an on-off transition. When the first state is the off state and the second state is the on state, the driver delays the assertion of the output signal to perform an off-on transition by a predetermined delay time, so that the off-on transition is delayed until all intended on-off transitions have occurred.
