Abstract
A controller circuit for controlling switching elements and controlling dead-time of the switching elements is configured to generate a phase difference voltage using voltage at a control node of a first switching element and voltage at a control node of a second switching element. The first switching element is configured to couple a first node of a supply and a switch node and the second switching element is configured to couple the switch node and a second node of the supply. The controller circuit is further configured to generate a first driving signal based on a first pulse width modulation (PWM) signal for the first switching element and the phase difference voltage. The first driving signal includes a voltage-controlled delay module. The controller circuit is further configured to generate a second driving signal for driving the second switching element based a second PWM signal for the second switching element.
