Abstract
A system comprises a first comparator, a second comparator, a pulse-width modulation (PWM) controller, and a ramp generator. The first comparator has a positive input coupled to a first ramp output of the ramp generator and a negative input configured to receive an input voltage. The second comparator has a positive input configured to receive the input voltage and a negative input coupled to a second ramp output of the ramp generator. The PWM controller is coupled to outputs and control signal inputs of the first and second comparators and has a control output. In some implementations, the ramp generator generates a high-side falling ramp for the first comparator and a low-side rising ramp for the second comparator. In some implementations, the ramp generator includes a first ramp generator for the high-side falling ramp and a second ramp for the low-side rising ramp.
