Hello Piet,
Best would be if you open the Webench design and exchange these components there as the tool calculates if the power dissipation is feasible or not.
BTW, the new transistor is CSD17579Q5A, right? I do not expect big influence by exchanging…
Part Number: TPS40077 Other Parts Discussed in Thread: CSD17579Q3A , CSD17577Q5A , CSD17579Q5A , CSD17577Q3A Dear team
There is a good news that we design in TPS40077 in customer's new project.
The spec is Vin=19V,Vo=12V,Io=12.5A.
Could you help…
Dear Brigitte,
Thanks for the explanation
In the first batch (250 pieces) we used the CSD17579Q5A!

Do you have an idea why the measured ripple is so high... See below for the ripple

Hi Hugo,
Thanks for promoting TI MOSFETs at your customer. Operating the CSD17527Q5A with a peak VDS of 29.3V is not a problem. What concerns me is there is not much margin in this design for component variation. Also, the FET breakdown voltage is reduced…
Other Parts Discussed in Thread: CSD16321Q5 , CSD17579Q5A , CSD87353Q5D , CSD87334Q3D In the WEBENCH design I did it came up with two discrete NexFETs. If possible I would like to convert them to a NexFET PowerBlock. But looking at the PowerBlock data…
Part Number: LM3488 Other Parts Discussed in Thread: CSD19533Q5A , CSD17579Q5A , Hi, guys. I'm trying to make two custom PCBs with the LM3488MMX/NOPB. Each PCBs will have the MSP432P401R MCU (3.3V).
1) 5V micro-USB powered boost converter to generate…
Hi na na 78,
1. The FET is there just so we could evaluate a different package FET. Q7 FET is what we tested with. Q5 can be removed.
2. Both were tested and are okay to use in a design. I find however, that they are both NRND. You can either of…
Part Number: BQ25713 A new circuit design using the BQ25713 was done. Unfortunately there were some mistakes that are now corrected and we are trying to test.
I am now able to communicate reliably to the BQ25713 via I2C (thank you tech support from…
Ian,
Sorry for the late reply. The Transient model nomenclature comes from the power products which may or may not need a transient and average (AC)model. The MOSFETs are transistor level based subcircuits and can be used in any simulation, hence the…
