In the U2 design, jumper J17 can be used to select between the switching frequency options shown in Table 2-2. If the desired option is not available, change one of the resistors to the value which sets the desired option.
In the U1 design, change the FSEL resistor to the value which sets the desired option.
|JUMPER SETTING||FSEL RESISTOR||SWITCHING FREQUENCY|
|1 to 2 pin shorted||17.4 kΩ||750 kHz|
|3 to 4 pin shorted(1)||11.8 kΩ||1000 kHz|
|5 to 6 pin shorted||8.06 kΩ||1500 kHz|
|7 to 8 pin shorted||4.99 kΩ||2200 kHz|
