... NXP Semiconductors 7.3 Masking and valley switching The MASK pin ensures that switch-on of the converter valley during ringing and not at a peak during freewheeling of the inductor. If the voltage level at the MASK pin is above 100 mV, then switch-on of the switching FET is prevented. If the voltage level is below 100 mV, then switch-on prevention of the FET is released and at the moment of valley detection the FET is turned on ...
