摘要
A system includes a multi-phase switching converter and a converter control module. The multi-phase switching converter receives an input voltage and that supplies an output voltage to a load via a plurality of phases. Each phase includes a plurality of switches, an on-time generator module that determines an on-time of the switches, and a switch control module that controls a switching frequency of the switches based on the on-time and a clock signal, and an inductance that connects the switches to the load. The converter control module varies the switching frequency without varying the on-time or varies the on-time without varying the switching frequency when current through the load varies.
