... N−Channel MOSFET Selection: The MC33567 was characterized ON Semiconductor’s MTD3055VL N−channel MOSFET. Other MOSFETs can be used with the MC33567 as long as power and stability requirements are met. Power: A MOSFET with a low drain−source on resistance (R DS(on) ) will insure the output voltage is not drastically reduced due to excessive voltage drop across the MOSFET ...
