Hello Adrian,
TPS2663 device can pass both EFT and Surge tests. You can refer to user's guide: TPS26630-33EVM Evaluation Module for TPS2663x (Rev. A) for test results of EFT and surge.
Can you provide the voltage level and source impedance for the…
Hi Aidan,
I have verified the concept through your simulation file. It looks good to me, please continue and evaluate on PCB.
For operating voltages up to 60V, we have integrated solution which runs on thermal regulation loop to drive large capacitive…
Hi Hossein,
Thank you for the informaiton.
For 5A, please go for TPS2663
For 20A case, you would need external FET based solution. please consider LM5069.
Best Regards,
Rakesh
Hello Magnus,
It would be more suitable to use an external current source and force current into ILIM resistor to control the current limit.
Do you want to change the current limit (on the fly) with software for TPS2663?
Part Number: TPS1663 Hi team members.
Please tell me the transient thermal resistance of TPS1663 (VQFN (24)).
It is not enough to calculate the transient heat loss precisely with Fig. 13 of the data sheet and TPS2663 Design Calculator .
Hi Ilya,
eFuse devices provide ouput short circuit protection along with FLT/ pin to indicate a Fault event in the system.
For 28V rail you can consider using TPS2660 , TPS1663 or TPS2663 family of devices
For 12V rail, you can have a look at…
Hello Thomas,
You can consider TPS2663 devices for Class-A performance with surge tests. You can find surge results for power line surge (500V, 2-Ohm Impedance) in the user's guide of TPS26630-33EVM : TPS26630-33EVM Evaluation Module for TPS2663x (Rev…
Hello Ingo,
For achieving Criteria-A performance with TPS2660, the output cap value has to properly chosen to provide the current to the load during the time of surge. For selecting the value of output cap for TPS2660, you can refer to equation 4 on…
Hi Greg,
Sorry, I did not fully understand the issue. Do you mean that during output short circuit, the supply source Vin is collapsing ? what is the current limit the source is set for ?
As you mentioned that you are new to the design. Can you pick…
