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 the 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:
