1. A circuit, comprising:
a current compensation circuit having first and second compensation inputs, and a compensation output, in which the first compensation input is coupled to an input voltage terminal and the second compensation input is coupled to a switching terminal; and
a one-shot circuit including:
a comparator having first and second comparator inputs, and a comparator output, in which the first comparator input is coupled to a voltage reference terminal and the second comparator input is coupled to the compensation output;
a switch coupled between the second comparator input and a ground terminal; and
a capacitor having first and second capacitor terminals, in which the first capacitor terminal is coupled to the second comparator input and the second capacitor terminal is coupled to the ground terminal.
