Abstract: The objective of this invention is to provide a boost circuit that reduces power consumption and prevents malfunctioning when the input voltage becomes greater than a target voltage for the output voltage. Control circuit module 5 sets both control signals HCNT2 and LCNT2 to low level “L” when the conditions “output voltage VBoost is higher than voltage OVREF” and “voltage (VIN+VOFFSET) is higher than output voltage VBoost” are satisfied. With this, in boost circuit module 7, switch SWH will be off and switch SWL will be on to forcibly switch to mode B. In mode B, because switch SWH is on, output voltage VBoost will be near input voltage VIN, and the power consumption can be reduced.
