Part Number: TPS40040 Other Parts Discussed in Thread: LM2748 , LM2745
Dear,
our client want to design a buck controller as the spec below:
Vin:3.8V
Vout:2.8V
Iout:40A
1. Why the current limit is 15A in TI.com
2. Is TPS40040 can change MOSFET…
Other Parts Discussed in Thread: TPS40040 I'm using the TPS40040 in a design. SwitcherPro do not able me to change the resistor RefDes R5 in my simulation (resistor that fix the output voltage), even if the RefDes text is in red!! It's poping me a window…
Hi Edwin,
(I am sorry for getting you confused...)
My question is does this device have a pre-bias startup function? Or not?
Another question is how this device behave at the pre-bias startup ? The duty increase gradually ? or increase immediately…

Hi Scott,
Has TI tested the Netra with a TPS659112?
Anil: No, DM8168 is tested with TPS40040 (GPIO based) and TPS40400 (I2C based)
Has TI tested SmartReflex with a TPS659112?
Anil: With respect to DM8168 it is not tested, SmartReflex is tested…
Part Number: TPS40422 Tool/software: Hi expert,
Customer used TPS40422 for 12Vin to 0.88Vo/40A and use the calculation tool for compensation but find the phase/gain margin is not good.
Would you please advise how to adjust the stability?
TPS40KType…
Ramgopal,
Your assessment of the bulk decoupling required is correct. You must calculate the required amount and validate it. The Hardware Design Guide (SPRABI2) discusses this calculation.
This bulk capacitance will affect the control loop on the…
