Other Parts Discussed in Thread: INA826

Dear TI

I can't use tps65131-q1 for dual positive and negative output web bench.

my design condition is below

Vin 3~5.5V(normal 5V)

Vout1 5V 40mA min~

Vout2 -5V 40mA min~

Automotive

(for example circuit include one ina826 with dual power)

do you suggest circuit example or web bench?

Hi Choi,

So your input voltage will vary from 3V~5.5V during operation? Is it possible to use a constant like 3.3V?

Hi Choi,

For TPS65131-Q1, too close Vin and Vout1 might be a challenge. This is also a challenge for our other dual output solutions. So may I know if the Vout1 could be raised up or the 5V Vin could be decreased?

Hi Yao

Vout1/Vout2 couble be raised up over +/-5V~15V

Hi Choi,

I recommend to raise up the VPOS not to make it close to Vin.
