Hello Robert,
no problem, thank you very much for the effort! I took your advice from the last post and switchted to the LM5005, which fits my requirements also very good. You also were right concerning probing.
Again, I really appreciate your efforts…

Part Number: TPS2553D Other Parts Discussed in Thread: TPS2553 , LM5005 Hello Team
My customer is using the TPS2553 as a load switch in the circuit below with overcurrent set to nominal 266mA. They are testing their boards and found on some boards, the…
Hi Kanemaru,
You can use the LM5005 WEBENCH model for further guidance. There is an internal 25uA current source contributing to slope compensation (see equation 2 in the LM25005 datasheet), and using a very large inductance could shift the emulated current…
Hello Geo,
Apologies for the delayed response.
The average value of the inductor current in the inverting buck boost topology is not same as the output load current (as in the normal Buck topology).
The average value of the inductor current is given…
Other Parts Discussed in Thread: LM5005 Hi,
I have a design with LM5005. Here are the main parameters:
Vin=48V
Vout=12V
Switching Freq=387kHz
Scope picture at swithing node:
My problem is that there is a huge high frequency noise at the switching node…
The LM5085 should be able to step down the voltage to 5.4V and deliever the nessessary current.
I'm not sure of the drop out voltage from 6V to 5.4V.
Try also perhaps LM5005 (integrated switch).
