Other Parts Discussed in Thread: TPS54318 When are use TPS54318 to generate 3.3V when the input voltage is 5v,the output voltage is 2.8v ,i measure the PH pin signal ,the duty cycle is 0.55,the vsns pin voltage is0.69v,the feedback resistor value are respetively…
Other Parts Discussed in Thread: TPS54318 Hi, Could you tell me about TPS54318? To solve the problem that an output voltage fluctuates, when load fluctuates. In that case,PG is NG status. Will you check the attached file? Customer is to manage the sequence…
Hi, Could you tell me about efficiency simulation. Customer simulated following conditions. ◇Vin=3.3V to 5V,Vout=1.1V,Iout=3A
I got the following questions about the simulation. 1.The reason more 5V is more efficient than 3.3V 8688.WebenchReportsServlet.p…
Other Parts Discussed in Thread: TPS54418 , TPS54318 Hi, Could you tell me about difference between TPS54318 and TPS54418. Customer is wondering whether to use the device. Customer want to choose whichever efficient.
I confirmed the data sheet. However, I could…
Other Parts Discussed in Thread: TPS54318 I'm currently designing a power solution to power one of the rails (1.2V) for an Altera FPGA. Referring to TI's slyt395b article, I decided to use the TPS54318 IC to power the 1.2V rail. Looking at the…
Other Parts Discussed in Thread: TPS54318 We have used step down SMPS TPS54318 in one of our designs. The SMPS generates 1.2V output from input of 5V. The maximum load current at 1.2V is around 1A. Now we have a requirement where we need to remove all…
Other Parts Discussed in Thread: TPS54318 My TPS54318 circuit won't start; I get zero volts out. I can see the SS pin ramp up to about 0.8V, and then drop to zero after about 3mS. The enable is high. Input voltage=5V.
What's going on? I have no idea…
Part Number: TPS54424 Other Parts Discussed in Thread: TPS54678 , TPS54318 , , TPS54335A
All newer devices with variable switching frequency (TPS54335A, TPS54318, TPS54678) I have worked with so far have formulas in the datasheet to calculate efficiency…
Other Parts Discussed in Thread: TPS54318 Hi, team,
I need to check one thing about TPS54318. Is there any PWRGD delay time of TPS54318? Or once the VSENSE voltage rises to the good condition above 93%, PWRGD MOSFET will turn off and pin voltage will turn…
Other Parts Discussed in Thread: TPS54318 , TPS54618 Hello,
TPS54318 θJctop = 1°C/W TPS54618 θJctop = 46.09°C/W
Both package is QFN 3mm x 3mm.
In my understanding, thermal resistance in similar package has similar thermal resistance performance…
