Abstract
A circuit generates an output voltage from an input voltage and includes a Pulse Width Modulation (PWM) controller. The PWM controller initiates a PWM pulse according to a first comparison that uses a Current Sense and Ramp (CSR) signal and an error signal. The PWM controller ends the PWM pulse according to a second comparison that uses the CSR signal and a threshold signal. The CSR signal is generated using a current sense signal and a ramp signal according to the input voltage. The error signal is generated from the output voltage and a reference voltage. In an embodiment, the circuit is one of a plurality of substantially identical modules, wherein one module is a master module. The master module generates an error signal used by each module. A clock input of each module is respectively connected to a clock output of another module to sequentially activate each of the modules.
