  • TPS61090: TPS61090 Boost convertor

    Part Number: TPS61090 Other Parts Discussed in Thread: TPS61092 Hello Freaks, This on is my first post here and I'm exacting help for the forum I'm using TPS61090 adj. DC -DC boost converter to get +5.0V from 3.7V Li-ion battery. I followed its design…

  • RE: TPS61090: TPS61090 won't boost, gets hot and output voltage falls down

    We replaced the TPS61090 IC, now things are different : - When powered up with a Lipo 1S (input voltage = 4.12V) we are now sometimes getting a bouncing output voltage down to 3.72V for few seconds and then back to 5V. Four out test, the load is our…
