IC693PCM300MP 根據(jù)電感、磁芯損耗、直流電阻和飽和電流選擇外部電感。通常，如果電感中的峰峰值紋波電流在50 kHz至100 kHz的頻率范圍內(nèi)接近飽和電流額定值，則磁芯損耗過大。如果可能，請使用線藝等電感器制造商提供的磁芯損耗計(jì)算器。在給定尺寸下，匝數(shù)越小的導(dǎo)線提供更高的電感，可以降低紋波電流和磁芯損耗，但會降低直流飽和電流并增加直流電阻。

IC693PCM300MP首先選擇耦合電容值，以使平均電荷相對于循環(huán)電荷較大（等于I外/開關(guān)頻率）。然后，計(jì)算電荷/電容以找到紋波電壓，紋波電壓不得超過直流伏特的一小部分;5% 是很好。請注意，陶瓷電容器在焊接后會隨著施加的電壓和時間而損失大量電容;因此，陶瓷電容額定值要非常保守。（村田制作所提供了繪制這些系數(shù)的在線工具。對于采用小型封裝的高 C × V 額定值的器件，這種隨施加電壓而損失的電容尤其如此。輸出電容和耦合電容使用相同的電容額定值通常很方便。
