Abstract
A circuit is configured to drive a switch mode regulator and to control the slew rate at a switching terminal of the regulator. The circuit includes first and second transistors coupled between a voltage supply terminal and a switching terminal, and includes third and fourth transistors coupled between the voltage supply terminal and the switching terminal. The circuit includes a fifth transistor coupled to the fourth transistor in a current mirror configuration and a sixth transistor coupled between the voltage supply terminal and the third transistor. The circuit includes a first resistor coupled between the voltage supply terminal and the fifth transistor, and includes a second resistor coupled between the sixth transistor and the second transistor.
