Abstract

An electrical system includes: 1) a buck converter; 2) a battery coupled to an input of the buck converter; and 3) a load coupled to an output of the buck converter. The buck converter includes a high-side switch, a low-side switch, and regulation loop circuitry coupled to the high-side switch and the low-side switch. The regulation loop circuitry includes a comparator with preamplifier gain adjustment circuitry configured to adjust a preamplifier gain of the comparator based on an overdrive voltage.
