Abstract:
A DC-DC converter includes a primary side sense circuit to detect a load current of the DC-DC converter based on reflected current from a secondary winding of the DC-DC converter to a primary winding of the DC-DC converter. A primary side diode models effects of a secondary side diode that is driven from the secondary winding of the DC-DC converter. An output correction circuit controls a switching waveform to the primary winding of the DC-DC converter based on feedback from the primary side sense circuit and the primary side diode.
