Operation Description
Noise Immunity
Noise from the current sense or the control signal may
cause significant pulse-width jitter, particularly in
continuous-conduction
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 SG6846B.
