Ripple and Noise
The test circuit setup shown in Fig D was used to
obtain the output voltage ripple. And Fig. E was used
to obtain the input reflected ripple current waveforms.
The output voltage ripple waveform was measured
across a 1µ
図Dに示す試験回路は出力ﾘｯﾌﾟﾙの測定に使用しており、入力ﾘｯﾌﾟﾙの
測定には図Eの波形を使用しています。全ての出力ﾘｯﾌﾟﾙ波形は1μFの
ｾﾗﾐｯｸｺﾝﾃﾞﾝｻを通して測定しています。
