For low voltage market, there are mainly two types of applications, DC-DC switching and DC applications. In a DC-DC application, Vout is not equal to Vin. It could be a step up or step down conversion; however, most of the cases are step down conversion, which means Vout will be less than Vin. The DC application is used for load switch, OR-ing and battery management. In these types of application, Vout is ideally equal to Vin and current is continuously flowing or not at all, like a lamp switch.
