Operation Description
Noise Immunity
Noise from the current sense or the control signal may
cause significant pulse-width jitter, particularly in
continuous-conduction mode. Slope compensation helps
alleviate this problem. Good placement and layout
practices should be followed. Avoid long PCB traces and
component leads. Compensation and filter components
should be located near the SG6846A.
