Part Number: TPS61070 Hi Jasper,
My customer have meet TPS61070 damaged issue, they found SW pin short to GND, fail rate about 3%, total 50/1400.
Schematic as below, customer said they have meet this issue before, but they change the inductor from 4.7uH…

I have a `Solar Study Light Project` for the Africans who has no access to electricity. Almost 10 different controller board samples that had been designed…
Hi,
note I didn't say UVLO - this is a bit odd. Our application is 3V out from 2 alkaline cells, so min Vin 1.8 max about 3.2. Approx 100mA output current. It broadly seems to work - and is essentially the datasheet circuit.
But in testing we've noticed…
Other Parts Discussed in Thread: TPS61070 Hi there!
I use the power supply based on the TPS61070. Normally it converts 3V to 5V @ load current from 1 to 30 mA. In this case I have no problem at all. When I need to switch input voltage from internal battery…
Other Parts Discussed in Thread: TPS61070 I'm using 2 x AA cells to power a small cct with two loads (processor and another chip) via the 61070, pretty much following the spec's reference cct/values.
Using a 10uF tantalum input cap with a .1uF…
Other Parts Discussed in Thread: TPS61070 , TPS61220 , TPS61291 Hey there,
I'm looking to use a TPS61070 at the moment to boost from two AAA Alkaline batteries. To be safe, I want to ensure that there is not too much noise on the output voltage with a boost…
Other Parts Discussed in Thread: TPS61070 , MSP430F5659 I've designed in a TPS61070 to step up a single cell lithium thionyl battery (2.8V-3.7V range) to 5V. I've got a few board that work flawlessly every time I hook them up they automatically output…
Hello Jim
Sorry I am busy on another issue before.
I am using TPS61070 in our many projects. It is provided 5V(from Li-iron) for small battery charging & buzzer. The total current consumption is below 300mA(@5V).
The problem is that the SW pin will…
