The circuit  has a 24V output and can deliver current up to 3 amperes. A switching frequency of 500kHz was chosen as a compromise between switching loss and the size of inductor L1. Increasing the value of gate resistance R7 will reduce EMI noise, but increase switching loss. A value of 4.7W was chosen as a compromise. At an input voltage of 12V, a full load of 3 amperes and an output of 24V, the conversion efficiency was 93%.
