Abstract
A voltage regulator circuit includes a high side (HS) transistor having a control input and a low side (LS) transistor having a control input. The LS transistor is coupled to the HS transistor at a switching terminal. A comparator has first and second inputs and an output. A first resistor is coupled to the switching terminal. A second resistor is coupled between the first resistor and the second input of the comparator. A capacitor is coupled between a second resistor terminal of the second resistor and ground. A switch has first and second switch terminals and a control input. The first switch terminal is coupled to the first resistor terminal of the second resistor, and the second switch terminal is coupled to the second resistor terminal. A delay circuit has an input and an output. The output of the delay circuit is coupled to the control input of the switch.
