Leading Edge Blanking

The adjustable Leading Edge Blanking (LEB) is used to

blank primary current spikes resulting from primary

switch turn-on. Implementing adjustable LEB allows

the system to ignore turn-on noise to best suit the

application without primary current sense distortion

from RC filtering. There are four settings available for

LEB, including zero. These settings are controlled via

the two bits in the ICLEBCON register.
