... Once a failure is detected, the FAIL pin can be cleared by recycling the EN pin or applying a complete power-on-reset (POR). If the detected failure is an Over- current time-out, the EN pin or a POR must be cycled/ executed to restart the part. , then the device shuts down all functions.

... Network Compensation Since this Boost converter is current controlled, a Type II compensation is needed. Analog Integrated Circuit Device Data Freescale Semiconductor COMPONENTS CALCULATION Note that before calculating the network compensation, all boost converter components need to be known. For this type of compensation it is recommended to push out the Right Half Plane Zero to higher frequencies where it will not significantly affect the overall loop ...
