Abstract
A switching regulator includes a power stage circuit and a control circuit. The power stage circuit operates a high-side switch and a low-side switch therein according to a high-side signal and a low-side signal respectively to generate an inductor current flowing through an inductor therein. The adjustment signal generation circuit in the control circuit generates an adjustment level according to the high-side signal, the low-side signal, and/or the inductor current, wherein the adjustment level is switched between a reverse recovery level and an anti-latch-up level, and is electrically connected to a low-side isolation region of the low-side switch. The reverse recovery level is lower than the input voltage. The anti-latch-up level is higher than the reverse recovery level to avoid a latch-up effect.
