PRODUCTION DATA
The device adds a compensating ramp to the switch current signal for all duty cycles. The slope compensation adjusts the peak current during the charging of the inductor to avoid instability of the system. As a result, the ideal slope compensation is defined as the output voltage divided by the inductor size as shown in Equation 10. The slope compensation, SC, can be configured with a resistor to GND connected to the RSC pin. The RSC resistor value, in kΩ, can be calculated using Equation 11, where SC is in A/µs and fSW is in kHz.
