Abstract
A circuit and method providing switching regulation configured to provide a pulse frequency modulation (PFM) mode of Operation with reduced electromagnetic interference (EMI) comprising an output stage configured to provide switching comprising a first and second transistor, a sense circuit configured to provide output current information sensing from an output stage and a current limit reference, a first digital-to-analog converter (DAC) configured to provide signal to the current limit reference, an adder function configured to provide a signal to the first digital-to-analog converter (DAC), and a linear shift feedback register (LSFR) configured to provide a signal to an adder function followed by the first digital-to-analog converter (DAC), and the LSFR receives a clock signal from said output stage.
