  • DUAL-CHANNEL CONSTANT ON TIME SMPS WITH SINGLE PHASE-LOCKED LOOP AND THE METHOD THEREOF
    Publication number: 20180269783
    Abstract: A dual-channel constant on time SMPS with a phase-locked loop. The dual-channel constant on time SMPS effectively controls the phase shift between the two power switching circuits by generating a phase error signal based on the switching signals which are used to control the power switching circuits, the phase shift between the two power switching circuits is kept to a desired degree by regulating the second switching signal.
