  • TPS61026: About shutdown sequence

    Resolved
    Part Number: TPS61026 Hi, Could you tell me about TPS61026 shutdown sequence. In the ON / OFF test of the customer, Vout and VBAT become 0V before EN, LBI pins. EN and LBI pins are kept at about 1V for 2 sec. Is there a risk of failure if this off sequence…

  • Re: TPS61026 start up

    Resolved
    You might want to use the equations in the datasheet (equations 4 and 5) to calculate the maximum inductor current. The maximum inductor current is going to be the average inductor current (equation 4) plus 1/2 the ripple current. Rearrange equation 5…
