As a follow up, I would also look at the CSD18531Q5A as an alternative. Power loss is higher than the CSD18540Q5B but it is a lower cost FET.
Thanks,
John
Part Number: TPS40170 Other Parts Discussed in Thread: CSD18531Q5A , , LM5145 Hello,
why WEBENCH designer shows Qty=2 for M1 transistor, but on PCB layout is only one? (check attached WEBENCH report)
This not happen with switching frequencies below preffered…
Hi,
I think that CSD18531Q5A is a good Mosfet but it is 60V rated and it might be not enough for Alcor design. I use them in 48V design but I am able to keep VM quite stable (really large bulk capacitance + precise brake chopper) and I keep amplitude of…
Part Number: DRV8711 Other Parts Discussed in Thread: CSD18531Q5A We are facing technical issue with stepper motor interfacing. We are using the DRV8711 Stepper motor driver along with CSD18531Q5A MOSFETS. And, we are using a 24V supply and the stepper…

One of my customer is designing medical project and request for RoHS3 compliant MoSFET's for buck boost application. The below suggested Mosfets are…
Dear Wang,
We are using "CSD18531Q5A" MOSFET, and the dead time is 850ns.
And, Driver register Configuration.
// DRIVE register st_gDriveReg.u8_mAddress = 0x06; st_gDriveReg.u8_mIDRIVEP = 0x00; st_gDriveReg.u8_mIDRIVEN = 0x00; st_gDriveReg…
Part Number: LM5117 Other Parts Discussed in Thread: CSD18540Q5B , CSD18531Q5A , CSD18563Q5A Hello, we are using LM5117 to realize a power supply as follows: 18Vdc input, 4,2V output 10A. It operates very well, cool and stable . BUT we are experiencing…
Hi Alcor,
Such long switching time is very suspicious, I use CSD18531Q5A with Qgd of 5.9nC at Vds = 30V, at 50V Qgd would be (it's just my guess) 50/30 x 5.9 = 9.83nC.
For a gate current of 150mA it should be 9.83/0.15 = 65.5ns but in reality it is…
Part Number: CSD18534Q5A Other Parts Discussed in Thread: CSD18543Q3A , CSD18531Q5A , CSD18533Q5A , I CAN import the Pspice models into ADS for: CSD18531Q5A & CSD18543Q3A.
But you cannot import the Pspice models into ADS (2016 or 2019, doesn't matter) for…
Hi Nikos,
Thanks again for your interest in TI FETs. After reviewing your requirements, I would recommend using 2 x high side and 2 x low side FETs in parallel in each phase of the sync buck charger. You can always remove one parallel FET if it is not…
