Hi Jasper Li,
Thanks for reply my question.
I also use the same interpolation method like your suggestions for my estimations.
My design needs 2V/lower than 2V input for 3.3V output at 1A, I already find your TI device close to what I need, TPS63021…
Hi,
thanks for the answer.
I asked this because in my design after the BQ24195, that I use mainly for battery management, there are a boost ( TPS61232 5V out) and a buck converter (TPS63021 3,3V out) and I wanted to know if the ripple current out…
Hi Christine,
You are correct about the input capacitance (Cin) requirement. Please follow the datasheet requirements of a 4.7uF minimum for it. For the output capacitance (Cout), please refer page 16, eq.7. This points at a min value of 5 times the…
Hi,
We have a problem with the step-up / step-down (BUCK-BOOST) regulator TPS63021 .
In particolar condiction that we can't reproduct, the TPS63021 Vin pin goes in short circuit.
The chip becomes unusable and must be replaced.
Someone can explaine…
Dear Chris Glaser,
I intend to use a LIPO as you already know. So I was wondering from the region 4.2volts to 3.4 volts is it more efficient to use a 0.1V drop out linear regulator ? or the TPS63021 which automatically switches to boost mode when voltage…
I do not know whether I should use a Linear drop out voltage regulator or a Switching one like TPS63021 to gain power to my circuit using a one cell LIPO (4.2 to 3.0 V 5000mAh)
both ARM and the SIM908 module needs 3.3 volts ideally.
SIM908 requires…
