Multimode digital SMPS controller IC for low-power management
This paper introduces a novel low-power digital future, are expected to run at frequencies beyond 10 MHz. In controller for high frequency dc-dc switch-mode power supplies addition, the demonstrated systems do not offer a digital (SNIPS) that is well-suited for integration in power management solution for pulse-frequency modulation (PFM), which at light systems of small handheld devices. The controller operates at loads largely improves SMPS efficiency [3]. programmable constant switching frequencies up to 20 MHz and In this paper we present a new low-power architecture that can change mode of operation to improve the overall SNIPS allows integration of digitally controlled SMPS in the existing efficiency. The key elements of the controller are a high and upcoming handheld devices. The controller, shown infrequency digital pulse-width modulator (DPWM), based on a . . .a segmented ring oscillator, and a signal-race based digital pulse- Fig. , operates at programmable switchMg frequencie...
