Hi llya,
1.I guess you want to keep VOUT be 3.3V-3.4V no matter what is the VIN present, right? If that, set OSEL to 3.3V is ok for your application. By this way, when VIN is lost, the TPS61094 will boost VOUT to 3.3V.
What I mean before is that the buck…

Hi Jhon,
If VIN >= VOUT, the device works in pass-through or by-pass mode, no matter which mode the device…
Part Number: TPS61094 Hi team,
Customer got some question on the bi-direction feature.
Does the bi-direction mean only under the bypass mode, and the current can flow from Vin to Vout or Vout to Vin, right?
And other modes, force buck, auto buck or boost…
Part Number: TPS61094 Hi, best regards.
I'm having troubles with power consumption using TPS61094 (IC1) in the schematic shown below.
The label BAT_LIPO represents a LiPo battery voltage range of 3V-4.2V.
IC11 is a buck-boost RP605K333B.
When…

I am working on design that uses TPS61094 to regulate the output of BQ25504 to 4.5V to remove the effect of MPPT. The TPS61094 is loaded…
Part Number: TPS61094 Other Parts Discussed in Thread: TPS631000 , TPS63901 Hi,
Best regards.
I have assembled the scheme as shown below, but the output is not at 3.3V. It seems like the TPS is always in bypass mode. Vout = Vin
I am supplying power with…
Hello Ilya,
Sorry for the delay, there is labor holiday at the moment and until Wednesday. Please do not expect too much detail before.

Part Number: TPS61094 Configuration: Input voltage 3.85V, * MODE and EN pins are tied together and connected to output via 100k pull-up resistor. * supercapacitor (SC) charging termination voltage set to 3.6V * output voltage option set to 3.6V * charging…
Part Number: TPS61094 Hi Best Regards
I want to use the TPS61094 in boost mode.
The condition are:
* Always the Vin will be a Li-ion Battery 3.3V-4.2V
* Vout voltage must be 5V.
* The TPS will supply a sensor, maximum current 300mA.
* No need Supercapacitor…
