This letter 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=200 mA which has the CR of 1.27.
