High Side Switch Vs Low Side Switch. High side and low side switches a low side switch is a mosfet or an igbt that is connected to the ground referenced and is not floating. A low side switch will be an n channel with the source connected to ground thus switching it off will isolate the ground.
One reason is that even when the transistor is fully turned on there is still a small voltage drop across it. Ir2110 is a high low side gate driver ic which is used with power mosfet and igbt. In a boost converter the source terminal of the mosfet is connected to the circuit ground which is referred to a low side mosfet.
Generally in a circuit you want to keep the ground connected and switch the power.
