App note: Medium power small-signal MOSFETs in DC-to-DC conversion


App note(PDF) from NXP on DC-DC medium power small-signal MOSFETs.

This application note explores different methods of DC-to-DC conversion. It includes some examples of DC-to-DC down-converters using small-signal MOSFETs.

  1. I don’t understand why the P-FET in the photo is connected backwards. When the FET is turned off won’t current flow through the body diode? I think there’s a mistake in the schematic. In the application note the next image of the spice model for the circuit shows the FET connected correctly.

    1. it’s an appnote, I think it is fair to say quite a few of them should be be taken with grain of salt
