A MOSFET is used in a boost-buck converter. The on-state loss is 4.2 W, and the switching loss is 2.8 W. The device is in TO-220 heat-sink package. it is desired to avoid a heat sink, and a parallel connection has been suggested. If a second MOSFET is added in parallel,

what is the loss in each part?

will a heat sink be necessary?
