Hello Biswajit,
Thanks for your interest in TI FETs. In the conduction loss equations, the inductor RMS current is multiplied by D, duty cycle, for the high side FET and multiplied by (1 - D) for the low side FET. This is because the high side FET conducts…
Part Number: LM5119 Other Parts Discussed in Thread: PMP10260 , PMP20818 , CSD18534Q5A Hi,
It is said that Synchronous Buck "Freewheel" FETs must have Qgd/Qgs <1?
As such, please advise why ti.com has two reference designs of synch bucks, which…
Part Number: LM5143 Other Parts Discussed in Thread: PMP31210 , LM5119 , LM5148 , LM5146 , LM5145 Hi, do you know why the LM5143 (Synch Buck controller) was used for this Synch Buck spec (PMP31210 ref design) of 20-58vin and 13.5Vout and 50A out?... PMP31210…
Part Number: CC3120 We are using the CC3120 in our product. After some time from powering up the device the wifi application repeatedly crashes with the following error:
wifi_bridge_log[15626]: [ERROR] - FATAL ERROR: Sync loss detected #012#015

Part Number: LM5148-Q1 Other Parts Discussed in Thread: LM5148 , LM5149 Hello,
I'm currently using the LM5149-LM25149 Calculator for the LM5148 Buck Converter (as the LM5148 one's is not available).
For the buck inductance calcul, I followed the…
Other Parts Discussed in Thread: MOTOR-DRIVE-FET-LOSS-CALC , SYNC-BUCK-FET-LOSS-CALC We are using Office 365 (macros are activated) and when I klick on Start FET selection and then on 3c "Click Here FET1" nothing happens. Only the sheet is flashing and…
Part Number: BQ25756 Hi,
We have previously made some queries. The case number was CS2169510. Since it was closed, I am writing my next query as follos:
To reduce the Power Loss, we are more inclined to use GAN FET. Our selected component is EPC23102ENGRT…
Part Number: CSD19501KCS Other Parts Discussed in Thread: MOTOR-DRIVE-FET-LOSS-CALC , Hi, In the MOTOR-DRIVE-FET-LOSS-CALC Excel sheet, the equations tab contains an equation to calculate RDS(on) with temperature. But I am unable to understand what ΔRDS…
Hi Team,
buck converter without sync mosfet (conventional buck converter) any application note or any schematic avalible for high side floted mosfet driving perpose.
Part Number: CSD95379Q3M Hi Team,
We've been trying to use the SYNC-BUCK-FET-LOSS-CALC to calculate the losses of CSD95379Q3M.
It seems like every time I press any of the '--> --> CLICK HERE <-- <--' buttons a new selection windows starts to open but…
