The device boost DC/DC controller has minimum on/off time as below table. Minimum off time should be specially taken care in system design. The SW node rising time plus falling time should be higher than minimum off time to avoid controller not turning off the MOSFET.
|Frequency (kHz)||Minimum Switch OFF Time (ns)||Minimum Switch ON Time (ns)|
|100 to 500||150||150|
|1818 to 2222||40||110|
