PRODUCTION DATA
The voltage between ISNS and ISNSGND is used for both boost DC/DC controller's current sensing and cycle-by-cycle current limit settings. When the cycle-by-cycle current limit is reached, the controller will turn off the switching MOSFET immediately and turn on it again in next siwtching cycle. This cycle-by-cycle current limit could be used as a common protection for all related DC/DC components (inductor, schottky diode and switching MOSFET) to avoid current running over their max limit. Cycle-by-cycle current limit won't trigger any faults of the device.
