aDDitionaL FeatureS
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:
•
•
•
•
•
•
•
•
Elimination of External Current
Sense Resistor
Overvoltage Protection with Hysteresis
Overpower Protection with Shutdown
UVLO with Wide Hysteresis
Thermal Shutdown with Hysteresis
Variable switching frequency
Digital Spread Spectrum
Peak current amplitude spreading
additional spreading and further reduces
EMI peaks

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
