Part Number: TPS61240 Just for confirmation on the tolerance on the feedback resistors:
Quote: The internal feedback resistor is R1=724k, R2=228K, and the reference voltage is VREF=1.2V. but the variation of the resistor is +-14%
So the absolute tolerance…
Part Number: TPS61240 Hi,
I probably will use the TPS6140 (boost converter) to generate 5V 1W (0.2A) from a single cell Li-Ion battery (4.2V down to 3.0V).
I'm trying to compute the inductor value that I need. Here is my design procedure :
Efficiency…

Hello,
I have some questions about schematic and board layout with TPS61240.
The TPS61240 that I use for my project didn't work property.
I assumed the problem is a board layout, So I updated the layout.
Could you review my…
Part Number: TPS61240 Dear,Sir
I am using TPS61240 IC in our project.I am facing issues related to the feed back path diode .
And due to that i am not getting the desired output.
If i replace the shottkey diode with 0E resistor i am getting proper output…
Part Number: TPS61240-Q1 Other Parts Discussed in Thread: TPS61240 Hello,
I have ordered evolution board of TPS61240 I am testing it using 100mA Load my power supply showing the drawn current is of 160mA I am using Electronic load as a load it can detect…
Part Number: TPS61240-Q1 Hello,
my customer is currently working on a new project and he is considering the TPS61240-Q1. However he wanted to know if we could please provide a Simetrix simulation model for this part. If not available then an unencrypted…
Part Number: TPS61240 Other Parts Discussed in Thread: TPS62141
Hi Experts,
We are doing an output short test. When shorted voltage output to GND, the output current continues to flow about 80mA.
VIN : 3.3V
VOUT : 5V
Is this a expected behavior?
Regards…
Part Number: TPS61240 Hi all, thanks for coming to make my life easier.
I am using the chip to power a set of OpAmp which should need around 50-60mA. For debugging purpose I am using a power supply to power up the TPS61240. So here is the hypothetical…
Part Number: TPS61240 Hello Team,
We are using TPS61240 step up in our new design. When I looked into the D/S I saw that acceptable undershoot for L pin is only -0.3V, while for Vout and FB its -2V. Isn’t a contradiction, cause more transients are expected…
