<p>A circuit (11) for controlling slew rate of a high-side switching element (6) in a load switch (5) is described. The circuit includes a variable current source (20) for setting a slew rate. The circuit also includes an amplifier (15) comprising a first input coupled to a fixed voltage source (19), a second input coupled to the variable current source and an output (18) for a drive signal. A feedback path (26) from an input terminal (13), connected or connectable to an output (14) of the switching element, to the second input of the amplifier, includes a series voltage-differentiating element, such as a capacitor (27).</p> |
