Hello,
I used the TI webbench to design a stepup circuit with the TPS61170, VIN = 3.3V VOUT = 24V Iout max = 30 mA.
The described components of webbench are used., and the circuit is working.
I tested the circuit standalone, under various loads, and it performed perfectly.
However when its connected to the other circuitry, (a couple of INA's), the PSU refuses to start up properly, while the load is only 4 mA.
I have tested the circuit again standalone, and connected a 10K resistor as a load, but then the PSU will not startup properly, and the output voltage remains at approx 10 / 11V.
Does this sound familiar to any one ?
Hope that somebody can point me in the right direction on how to resolve this, because I am a bit lost.
Best Regards,
Robin
