Other Parts Discussed in Thread: TPS61099
Hello,
I am using a TPS613221A for stepping up from 2.0V to 3.3V. According to the TPS61322 family datasheet, it is possible to increase the output current capability of the design by adding an external Schottky diode. In fact, an example is given in the family datasheet, but for 5V output.
As per 9.2.1.2.2, the estimated output current for Vin=2.0V, Ilim=0.75A (min), Ilh/2=0.1A, eff=0.7 should be Iout around 276mA (max).
My question is: how much can the output current be increased (estimation) by adding an external Schottky diode? Unfortunately, the family datasheet says nothing in this regard.
Thank you!
