2.1.2 Analog Comparator

The Analog Comparator (AC) is configured to compare voltages on external inputs. As the AC generates the PWM signal used to control the switching transistor, the output is routed to a pin. The comparator must have a fast response time. As a result, the power profile setting with the shortest response time and highest power consumption is chosen as a tradeoff since the power profile setting controls the current through the comparator.
