Jasper Li,
Regarding LBI Problem, we are unable to check that out because our all TPS61090 IC's got destroyed.
We have now already purchased fixed 5.1V output type TPS61092 and also redesigning the board as per document SLVA773 and evaluation module…
Other Parts Discussed in Thread: TPS61091 , TPS61090EVM-029 , TPS61090 , TPS61020 Hi,
Referring to TI SLVS484C (JUNE 2003–REVISED DECEMBER 2014) datasheet, Figure 6 on Page 7 states this parameter of TPS61091.
Q1. How does the TPS61091 generate 5V…
Yes, in forced PWM mode, the IC maintains a constant switching frequency with lower output ripple. You can order the EVM here, http://focus.ti.com/docs/toolsw/folders/print/tps61090evm-029.html , and see the performance difference, if you like.
The TPS61090…
