PRODUCTION DATA
The ramp amplitude, soft-start time, and current limit settings are programmed with a single resistor, RMODE, between MODE and AGND. Table 7-4 lists the resistor values for the available options. It is required to use a 1% tolerance resistor or better. See Section 7.3.10 for the corresponding current limit thresholds for the "High" and "Low" settings.
