To achieve high efficiency a Schottky diode should be used. The current rating of the diode should meet the peak current rating of the converter as it is calculated in Peak Current Control. Use the maximum value for ILIM for this calculation. See Table 5 and the typical applications for the selection of the Schottky diode.
