Other Parts Discussed in Thread: TPS40303 , CSD16325Q5 When creating design for TPS40303 for Vin=3.3V, Vout=1.00V/20A
1)I am not able to choose other M2 (lower FET), but only M1.Why?
2)Why when choosing ME FET from TI, I can not get any M2 FET from…

Part Number: TPS40305 Other Parts Discussed in Thread: TPS40303 , TPS62130 , TPS82130 Hi -
I have a design that uses the TPS40305 configured in a feedback regulated constant current configuration to deliver 26A to an LED. This design has been adapted…
Hi John,
So seems it triggers thermal shut down on our board.
I used the below formula and calculated the power loss of TPS40304.
Driver loss: Ptypical=Vdd* Fsw *(Highside Qg typical+ Lowside Qg typical)=12V* 600Khz*(49nc+49nC)=705W
Pmax=Vdd…
Hello,
This device is not recommended for new designs.
Please check LM27403 or TPS40303 device or similar.
You could also use Webench to enter your design specification and get recommendations as what device may be able to meet your requirements. …
Alexander,
BSC009NE2LS has Qg=80nC when used as high side fet and 43nc as sync fet. When you use 2 in parallel, total Qg=80+80+43+43=approx 240nC
The current requirement from BP regulator is Qgtotal x Fsw= 240nC x 600kHz = 144mA. Now you can see the…
