  • TPS51604-Q1: mode transition condition (FCC mode <-> very-low-power mode)

    Resolved
    Part Number: TPS51604-Q1 Please tell us the mode transition condition. FCCMVLPM. In FCCM, /SKIP = H and PWM = L are set. If /SKIP input voltage is changed from H to 1.6V, will the mode change from FCCM to VLPM? (PWM remains fixed at L.) If /SKIP input…

  • RE: LMG1205: Question for the number of MOS could be drived.

    Resolved
    Hi Qianru, It looks like the closest fit for this project in a similar sized package is TPS51604 . This half-bridge driver has a 2mm x 2mm sized package (compared to 1.8mm x 1.8mm) and looks like it can support currents well above the needed threshold: …

  • TPS51604 very low power mode

    HI Does we need to set tri-state at both SKIP and PWM pin in very low power mode? Or should we to set tri-state at only "SKIP pin"? On the datasheet it is described like below. (Page 11) 「When both SKIP and PWM are tri-stated, normal opera…
