A 0-to- 10μF Off-Chip Output Capacitor-Scalable Boost Converter Achieving 96.68% Peak Efficiency

This paper presents an off-chip output capacitor (CO)-scalable (OCS) boost converter. The proposed OCS boost converter is possible to operate both with and without the off-chip CO. In addition, it operates in a whole conversion ratio (CR) range over 1 while maintaining a small current ripple of an inductor, resulting in a high efficiency with an inductor of which inductance is small, irrespective of the CO capacitance. The converter was fabricated in 130-nm BCD process and shows a peak efficiency of 96.68% at VIN = 5.5 V, VO = 7 V and IO=200mA which has the CR of 1.27.

Abstract

This paper presents an off-chip output capacitor (CO)-scalable (OCS) boost converter. The proposed OCS boost converter is possible to operate both with and without the off-chip CO. In addition, it operates in a whole conversion ratio (CR) range over 1 while maintaining a small current ripple of an inductor, resulting in a high efficiency with an inductor of which inductance is small, irrespective of the CO capacitance. The converter was fabricated in 130-nm BCD process and shows a peak efficiency of 96.68% at VIN = 5.5 V, VO = 7 V and IO=200mA which has the CR of 1.27.
