  • TPS61288: Not getting the correct boost voltage

    TI Thinks Resolved
    Part Number: TPS61288 Added this part to our BOM and reused the example circuit, replacing a resistor to make 8V output instead of 12V output. We are only getting 3.7V output, which is the same voltage that is the input of this boost.

  • TPS61288: output voltage issue

    TI Thinks Resolved
    Part Number: TPS61288 Hi team, Input 3.6V, output 12V. Everything is OK in PFM mode. When the load is increased, more than 1 a of current is output, the inductor whistling (inductance is 104CDMCDS-2R2MC as recommended in the data sheet) and the output…

  • RE: TPS61288: Same input and same output

    Hi Zuhaib, According to your application requirement, I agree with Fergus's words. TPS61288 and TPS61022 are both ok. But TPS61022 is more suitable because the current limit of TPS61288 is too large which will need you to choose inductor with higher saturation…

  • TPS61288: Drive LED from the current which flows when EN=OFF

    TI Thinks Resolved
    Part Number: TPS61288 Hi team, In the original thread, output voltage is existing when EN=OFF. Can the customer drive LED (20~30mA) from this output? Regards, Hayashi

  • TPS61288: Vout exisiting when EN=LOW

    Resolved
    Part Number: TPS61288 Hi team, Customer notice Vout is +3.65V with Vin=+4V, EN pin=LOW. I think output is 0V because TPS61288 is Synchronous Rectification. Is it a correct behavior? Regards, Hayashi
