    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

    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.
