Hi
it should be more easier if using lithium-ion battery. power the GSM module directly with the battery. and a buck converter generating 3.3V for the other device. t but battery lifetime could suffer as the battery voltage should be higher than 3.3V…
Hi Daisuke,
Even though there is no load at Vout, converter will still have a pulse of switching at intervals (so called power save mode operation). When measuring Iq, we should exclude the power consumption of this switching. Adding a little higher…
Other Parts Discussed in Thread: TPS61201 Hi,
I am designing a battery powered circuit in which the sleep mode current should be as low as possible. I am using interrupt wakeup on a microcontroller. This device will take maximum current of around 700mA…
Other Parts Discussed in Thread: TPS61200 , TPS61020 , TPS61201 , TPS61025 , TPS61070 , TPS61261 Hi Chris,
this is an old topic, I am evaluating using TPS61200 to replace TPS61020, compare 1.8V input and 3.3V output.
TPS61025 is way higher than TPS61201…
Any suggestions on how to protect from reverse battery insertion by the user (AAA cell, 1.0-1.5v) with minimal losses?
When the battery is low (about 1.0v) a diode has too much drop, and a series FET's Vt probably not adequately controlled at such a…

Hi,
Kindly clarify my below Query as soon as possible.
What is the current output of TPS61200 @ 3.3V
What is the current output of TPS61201 @ 3.3V
Part Number: BQ25505 Other Parts Discussed in Thread: TPS61201 , Hello,
i have a question regarding simultaneous charging and discharging.
we are using the BQ25595 to charge a 100mAh (3.7V) LiPo Battery with 5C charge / discharge rating.
The input…
Part Number: TPS63070 Other Parts Discussed in Thread: TPS61201 , TPS61200 Hi! Could Vaux output of TPS63070 be used for reverce polarity protection as it shown on page 20 TPS61201 datasheet ?
I have tested this feature on TPS61201 and it worked well…
Part Number: TPS61201EVM-179 Other Parts Discussed in Thread: TPS61201 , TPS61200 , BQ25505 , BQ25570 , BQ25504 Hello,
I am a French student in electronic engineering.
I began to test the TPS61201 booster last week with the evaluation board.
However…
Thanks again Minqiu,
The issue with TPS61201 is that it will continue to operate in power save mode (>4uA) even when my microcontroller is in deep sleep (< 1uA). It seems to be a waste of power to keep the TPS chip running when its not required. That…
