Other Parts Discussed in Thread: TPS7A53,
now i have one question on TPS7a53 for low VIN input application, could you please help provide the total solution for it? thanks.
application request: Vin = ~1.4V, Vout = 1.15V (exactly), Iout <=2.5A, automotive EE.
chip: TPS7a53-q1 is one candidate
question: from d/s, the dropout voltage is <=320mV @3A with Vias =0. from the picture shown below, when Vbias is used, the headroom could be much smaller (indicated in figure21). this is helpful for me as I also consider to use Vin = 1.35V to get 1.15V output. so please help check if I can design this with Vin=1.35V and BIas voltage is set as 6.5V? If yes, if we can use the resistor divider (10K + 10K) to generate the 6V bias voltage? any better bias voltage is recommended here?
btw, can you help attach the total "verified solution for it? thanks.
