Efficiency enhanced Single-Inductor Boost-Inverting Flyback converter with Dual Hybrid Energy transfer media and a Bifurcation Free Comparator

A Dual Hybrid Energy transfer media (DHE) Single-Inductor Boost-Inverting Flyback (SIBIF) DC-DC Converter is presented. To increase the converter efficiency, two flying capacitors as well as an inductor are adopted as additional energy transfer media. Furthermore, in order to remove the bifurcation...

description	A Dual Hybrid Energy transfer media (DHE) Single-Inductor Boost-Inverting Flyback (SIBIF) DC-DC Converter is presented. To increase the converter efficiency, two flying capacitors as well as an inductor are adopted as additional energy transfer media. Furthermore, in order to remove the bifurcation problem occurring in the SIMO type converter, a Bifurcation Free Comparator (BFC) is adopted. The proposed chip is implemented in a 0.5-μm power BCD process and operates at 1.25 MHz with a max efficiency of 89% at an output power of 600 mW.
