Abstract
A device includes a first amplifier and a second amplifier. The first amplifier includes an inverting input configured to be coupled to a feedback node of an output of a power converter, a first non-inverting input configured to couple to a first voltage node, a second non-inverting input, and an output. The second amplifier includes an inverting input coupled to the output of the first amplifier, a non-inverting input coupled to a second voltage node, and an output. The device also includes a first transistor coupled to the output of the first amplifier and having a control terminal coupled to the output of the second amplifier, a capacitor coupled to a ground node and to the second non-inverting input of the first amplifier, and a current node coupled to the capacitor.
