Abstract
A novel single-inductor-dual-output (SIDO) boost
regulator with sequential-control is presented. This control c an
handle large loads or unbalance d loads with minimized cross
interference between channels. A c onstant-charge-auto-hopping
(CCAH) control is also presented to further extend the power ha n-
dling capacity of the regulator with a predictable system switching
noise spectrum. The switching frequency of the converter can
be automatically hopped between 1 MHz and 1 MHz/N where
