Operation Description (Continued)

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 SG6846C.
