  • RE: TPS61089: Vout =12v ,Iout=4.5A

    Resolved
    Dear Sir, The schematic is OK if the Vin is >=5V. For TPS61088, the internal logic circuit is supplied by the higher voltage of Vin and Vout. So for your application, at startup, the internal circuit is supplied by the Vin, after startup, it is supplied…

  • RE: TPS61021A: is this ic suitable for my application?

    1V inpus is too low, even big can't help. if the 1v input is a must, then you can refer to the TI design PMP9772 .

  • RE: TPS61200: Single solar cell charger with higher current output?

    we don't have a device that can support this output power for 0.5V input. you can use two IC solution. a TPS610987 generating 4.3V to power the TPS61088 VIN pin, and TPS61088 is used for the main power converting. as the reference design " www…
