Abstract

The proposed dual-path buck converter for Internet-ofThing (IoT) applications and portable devices reduces the inductor current and voltage stress to achieve 96.1% peak efficiency. With large voltage across flying capacitor, small size of flying capacitor is used to accomplish 0.671W/mm2 power density. By applying the ground noise cancellation, the load regulation is improved by 1.11%. The overshoot suppression feedback suppresses the overshoot to 45 mV and accelerates transient response in 6μs with a load variation of 2.5 A.
