Part Number: TPS61040
Customer Pilot feedback when they use TPS61040DBVR in the Smart meter,Vin 5V Vout 12V/40mA，then found some devices Vout only 4V and SW PIN ,below shows the pictures of schematic and good device&failure schematic.
Pls kindly help…
Part Number: TPS61040-Q1 1) What is the PSRR value(Frequency 10Hz to 10Mhz) for the Boost converter?.
2) We are trying to measure the PSRR value. Note : The input voltage is 3.3V & Output voltage is 6V
Our test set up is injecting noise (Modulating…
Part Number: TPS61040-Q1 Other Parts Discussed in Thread: TPS61040 Hi,
we are using the TPS61040-Q1 Boost converter for converting the 3.3V to 6V. Please find the schematics
Attached the power sequence of this converter
The Yellow color represent the…
Part Number: TPS61040-Q1 Hello,
1) What is the accuracy of the boost converter?
2) What is the PSRR?
3) What is the rise time of the output voltage when the power supply turns ON.
Kindly share soon as possible.
Thanks & Regards,
For TPS61040, the assembly is a little special, shown below.
So the red areas in SAM picture from TOP is delamination located between the die pad and mold compound . And delamination in this area has no risk and will be ignored .

excuse the delay getting back to you, I just received my evaluation board for the TPS61040 and got it on the bench. This board is giving very strange results. It is the -001 board that produces 18V output from, say, a 3.3V input. With no load…
Part Number: TPS61040 Other Parts Discussed in Thread: LM5001 dear support team:
my circuit board need a 28v power rail,and there only one 24v power source.
since TPS61040 Vin range from 1.8v to 6v.so i add a 20v zener diode between the 24V and…
Part Number: TPS61040-Q1 Hi ,
Can I place the feedback circuit behind the capacitor C2, as indicated by the red line below,What are the risks if i do this, how do you suggest to place it reasonably? Tks
