OPERATIO
Using the LTC3783 for Buck Applications
As shown in Figure 12, high side current sensing also
allows the LTC3783 to control a functional buck con-
verter when load voltage is always sufficiently less than
LTC3783
VIN. In this scheme the input voltage to the inductor is
lowered by the load voltage. The boost converter now
sees a VIN’ = VIN – VLOAD, meaning the controller is now
boosting from (VIN – VLOAD) to VIN.
