  • RE: TPS61288: TPS61288 design

    Resolved
    Hi, Fergus: For some reason, I didn't receive the P MOSFET yesterday and couldn't test it. Yesterday I sent you a blank schematic, I don't why. resending.... In the new schematic, I move the AS431 to the output side. You can see how tough…

  • TPS61288: TPS61288

    Part Number: TPS61288 Hi, I need your help desperately. With E2E help, I built a prototype to test, see attached schematic. it consists of 2 portions: TPS61288 boost circuit and a Vin clamp/cut-off circuit (D1,Q1,Q2, D3). Design goal: Battery voltage 8V…

    Hi, Fergus: I order TPS61288 sample, it's too small. I can't use breadboard to build prototype for verification. I prefer SOIC or small pitch SOC (I can solder wires to the pins and use copper foil for heat dissipating). I search TI website, only find…

  • TPS61288: Review of circuit & Queries on Layout

    Part Number: TPS61288 Queries are as listed below: Do we need to short AGND & PGND? a) If yes short directly or use Ferrite Bead in series to join them ? b) If no, then how to route AGND & PGND with a 2-layer board of 1 ounce on each side ? c…

  • 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

  • TPS61288: SOO mode

    TI Thinks Resolved
    Part Number: TPS61288 Hi Sir, may we understand this SOO mode, under normal circumstance, the ripple of PFM is large than PWM? right. but because TPS61288 has SOO mode, it can make PFM ripple smaller than PWM? under light load.
