PRODUCTION DATA
The switching frequency of the device can be selected by connecting a resistor (RFSEL) between the SYNC/FSEL pin and AGND. The frequency options and their corresponding programming resistors are listed in Table 7-1. It is required to use a 1% tolerance resistor or better.
RFSEL ALLOWED NOMINAL RANGE (1%) (kΩ) | RECOMMENDED E96 STANDARD VALUE (1%) (kΩ) | RECOMMENDED E12 STANDARD VALUE (1%) (kΩ) | Fsw (kHz) |
