Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: TPS40041 Hi Team
Let me ask about SCP.
Is the detection of SCP the ON resistance of the high side FET or low side FET?
I found in the datasheet, ”the SN0805016 uses the RDS(on) of the upper MOSFET switch as the current sensing,
but…
Part Number: TPS40041 Hi Team
Regarding design hint in total gate charge
=>It is mentioned in datasheet that "The upper switch MOSFET’s gate charge should be no less than 60% of the synchronous rectifier’s gate charge...."

Part Number: TPS40041 Other Parts Discussed in Thread: TPS64203 , LM5169 , LM5164
Hi,
I'm in need of a synchronous (for high efficiency) DC-DC buck converter with a 120V (max) input and 3V output. Is it possible to use TPS40041 where VDD is initially…
Part Number: TPS62101 Other Parts Discussed in Thread: TPS62110 , TPS62097 , , TPS54610 , TPS40041 , TPS40057 I would like to run simulations with this part, but I cannot find it in PSPICE for TI.
As shown below, there is a jump from TPS62097 to TPS62110. …
Other Parts Discussed in Thread: TPS40041 Hi,
we use the TPS40041 DC-DC-controller with 5V input and 1,0V output voltage for an application using the TMS320DM8168CCYGH.
The schematic is very similiar to the evaluation board DM816x/C6A816x/AM389x EVM from…
Other Parts Discussed in Thread: TPS40041 We have some stability problems with our DC-DC-regulator design using TPS40041.
At high current the system gets unstable and the TPS40041 turns off (Short Circuit Protection?), also the calculated max current wasn…
Other Parts Discussed in Thread: TPS40041 I have some issue which no start up at full load(5Vin 3.3Vo 20A), the circuit has two same FET in upper and bottom side.
The start up is ok at 50% load condition, but fails at full load, so I am wondering it happens…
Part Number: TPS40040 Other Parts Discussed in Thread: TINA-TI , , TPS40041 Tool/software: TINA-TI or Spice Models Hello All,
I have downloaded TPS40040_AVG model from TI website & ran the encrypted model in OrCad PSpice 16.6. My question is that, does…
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?
