Other Parts Discussed in Thread: TPS54427 , TPS54227 Our customer uses the resistance of EN as shown in the attached figure.
About TPS54427, does 225~900kΩ mean to RB?
And please tell me the recommended value of RB when VEN is 5V.
Part Number: TPS54427 Hi All
I have some noise in this design:
I measure this signal on the output side of the inductor (L1):
Any ideas what causes the spikes _before_ the level changes?
Other Parts Discussed in Thread: TPS54227 , TPS54627 , TPS54427 Hi,
My customer has questions.
Datasheet P15 of TPS 54427, From the Power Supply Recommendations section, Vout ÷ 0.65 or more is required.
further, The voltage drop due to Rds is added…
Due to my customer want fix inductor at 4.7uH(DCR=0.04ohm/Irms = 5.5A Isat is 10A).
application is 12Vin to 5V/3A and 12Vin to 3.3V/3A.
I run wench bench. the 5 Vout/3A can be use. but 3.3V seems no recommend.
and i see DS that inductor should…
