PRODUCTION DATA
The following design guideline provides a component selection to operate the device within the recommended operating conditions. Using the FSW pin, the design can be optimized for highest efficiency or smallest solution size and lowest output-voltage ripple. For highest efficiency set FSW = high, and the device operates at the lower switching frequency. For smallest solution size and lowest output voltage ripple set FSW = low, and the device operates with higher switching frequency. The typical values for all measurements are VIN = 12 V, VOUT = 3.3 V, and T = 25°C, using the external components of Table 9-1.
The component selection used for measurements is given as follows:
