Abstract
A low-power digital pulse-width modulator (DPWM) architecture for high frequency dc-dc switch-mode power supplies (SMPS) is disclosed that is well-suited for integration in power management systems of small handheld devices. The DPWM can operate in a stand-alone mode, without external clock, and can be implemented on a portion of silicon area needed for other DPWM solutions. In addition it has low power consumption and provides a good linearity of the input-to-output characteristic, also not characteristic for other architectures.
