Abstract
This paper proposes a Boost DC-DC switching converter with a 5V output voltage. By operating in CCM mode, it combines a digital pulse width modulator (DPWM) with a conventional analog pulse width modulator to enhance the input range and reduce the inductor inrush current greatly. With the DPWM technique, the boost converter can operate at an input voltage from 1.2V to 4.2V, while generating a output voltage up to 5V in TSMC 0.25um 5.0V CMOS technology. The measured peak efficiency of the switching converter is up to 97%.
