Each nano module is optimized to achieve high VOUT accuracy. Equation 1 shows that, by design, the output voltage is a function of the VCON voltage and the gain from VCON to VFB. The voltage at VCON is derived from VREF. Therefore, as shown in Equation 3, the accuracy of the output voltage is a function of the VREF × GAIN product as well as the tolerance of the RT and RB resistors. The typical VREF × GAIN product by design is 5.875V. Each nano module's VREF voltage is trimmed so that this product is as close to the ideal 5.875V value as possible, achieving high VOUT accuracy. See Electrical Characteristics for the VREF × GAIN product tolerance limits.
