PRODUCTION DATA
The SPSP pin can be connected to GND to disable spread spectrum. The pin can be connected to VCC to enable spread spectrum. The pin can also be connected to GND through a resistor to enable spread spectrum with ripple cancellation. This actively reduces the output ripple associated with spread spectrum which arises from the inductor current ripple amplitude modulation caused by the spread spectrum frequency modulation. The value is typically approximately 20 kΩ and can be more precisely calculated using Equation 4.
