The CS1600 uses a proprietary digital control algorithm to shape conducted EMI emissions, resulting in significantly reduced EMI filter requirements. Digital EMI Noise Shaping consists of three major components:
• Variable switching frequency °° The average switching frequency is varied with respect to the line voltage spreading energy over a wide frequency band.
°° The switching frequency is highest at the peak of the input voltage which minimizes peak currents
• Digital Spread Spectrum °° Shapes colored noise eliminating EMI noise spikes
• Peak current amplitude spreading provides additional spreading and further reduces EMI peaks
