PMP9772: Maximum output voltage and current capapility?

Part Number: PMP9772
Other Parts Discussed in Thread: TPS61088, , TPS40210, TPS43061

Hi TI,

TPS61088 can give 12V,4.7A (56 W) output at 60 degree celcius for input range 6V - 8.4V (according to WEBENCH designer). But our input range is 2.5V-4.2V and we want to drive 45W-50W load.

So,can PMP9772 fulfill our requirement?

What maximum output voltage and current PMP9772 can give?

    Hi Sir,

    PMP9772 is mainly for the low input voltage application. Especially fit for the super cap input which Vin is between 0.9-2.7V. As the power stage convert use TPS61088, so the maximum output power is limited by the peak switch current of the TPS61088, which is around 11A. That is when Vin=2.5V, Vo=12V, the maximum Io=(11/1.15)*2.5*0.9/12=1.79A.  Where 1.15 is the peak-peak inductor current ratio, 0.9 is the conversion efficiency.

    So for your application, please use s boost controller like TPS40210 or TPS43061.
