Abstract

In this paper we have presented a single inductor single output dc-dc synchronous boost converter using 5MHz switching frequency, ultimately reducing the inductor and capacitor sizes. Synchronous rectification has been employed. In the feedback loop we proposed a technique of smooth loop handover. For the dynamic load conditions we propose another technique to reduce ripples at higher loads. Control logic and buffer blocks are designed to generate proper signals to drive power MOSFETs. Input supply is 1.8V, switching frequency is 5MHz and output is 3.7V.
