Abstract
A buck-boost regulation methodology operable, in one embodiment, with a single inductor, four-switch (S-S) buck-boost regulator configured for DCM. Buck-boost transition switching control is operable when inductor charge time exceeds a max charge time, and inductor discharge time exceeds a max discharge time, and includes: (a) during charge transition cycles, at the end of the max charge time, if Iis less than a predetermined peak current I, switching Son (grounding the output side of the inductor) and Soff, causing Ito increase (a rapid SScharging current ramp), until Ireaches I, and (b) during discharge transition cycles, at the end of the max charge time, if Iis greater than zero, switching Soff and Son (grounding the input side of the inductor), causing Ito increase (a rapid SSIdischarging current ramp), until Ireaches zero.
