Other Parts Discussed in Thread: LMR36520
Hi. The customer's bus for power supply and communication requires 24V. When using TPS61170 in the occasions where boosting is required, abnormal noise occurs, which is preliminarily considered to be caused by the piezoelectric effect of the output capacitor (MLCC). However, there is no noise when using LMR36520 in some step-down occasions. Could you help answer the following questions:
For quickly change load, is there any key parameters of controller that can lead to noise issue? In other words, what parameters of controller should be considered?
