Part Number: TPS63901 Tool/software: Hello, I have a problem with my TPS63901. I have designed it to set 3.4V with SEL pin high and 3.0V with SEL pin set low.
With SEL pin set low, the chip outputs 3.0V, but with SEL pin set to high, it outputs 1.8V…
Part Number: TPS63901 Other Parts Discussed in Thread: TPS631000 , TPS631010 , TPS631011
Tool/software:
I will be using these two batteries for my product.
1) LiFePO4 - 2V to 3.65V
2) Li-Polymer - 3V to 4.2V
Can TPS63901 deliver an output…
Part Number: TPS63901 Hi
The package size of this product we tested is not consistent with the datasheet. The datasheet is 1.49, but our measurement is 1.512
Could you please help to confirm why such an anomaly occurs? Is there a tolerance range …
Part Number: TPS63901 In the datasheet, Pad B2 is an inner pad and « must not be left open »
Given that it needs to be connected to a resistor, what would be the recommended way to escape this pad?
If a via is used, what would be the recommended…
Part Number: TPS63901 Other Parts Discussed in Thread: TPS631000 We are working on a design with a LTE-M cat1 modem (nRF9160). We are considering using the TPS63901 in this design. The main reason is that this IC has a low quiescent current, because the…
Part Number: TPS63901 Other Parts Discussed in Thread: TPS62040 , , MSP430FR2475 Tool/software: Hi,
I have a problem with the buck-boost converter. when there is no load i don't have a stable current usage.
When the PCB is in power down it should…
Part Number: TPS63901 Hi,
As recommended by datasheet - I am using RCFG1/2/3 resistors with a tolerance of ±1%, temp coefficient better than ±200 ppm.
However, for my nominal selections of (SEL=High) 1.8V (CFG1=0-ohm), I get 1.794V, - and - for 3V…
Part Number: TPS63901 Other Parts Discussed in Thread: TPS631010 Hi,
We plan to use the TPS63901 in a space constrained design. In the worst case its power input can be as low as 3.8 V while it outputs 5 V.
On the datasheet plot (Figure 8-4) the current…
