Abstract
In this letter, we report a concept of integrating a monolithic buck converter power IC with in-package bondwire inductors. The power IC containing all switching devices, driver circuitry, and control logic was designed and fabricated with a standard 0.5-μm CMOS process. Mutliturn bondwires with and without ferrite epoxy glob cores are used as the filter inductor in the buck converter.A prototype system-in-package converter with an output voltage and current of 2.5V and 120mA was built to operate at frequencies up to 5MHz. The power level of the prototype buck converter is scalable by increasing the size of the active power switches. © 2006 IEEE.
