  • RE: TPS7A78: TPS7A78

    Resolved
    Hi Y.Ottey, As discussed, "The voltage from AC+ to GND will have 30V max and AC- to GND will have 30V max, per the datasheet and the clearance needs to be set accordingly". When you mention input voltage, are you talking about the AC voltage…

  • TPS7A78: as 15 and 5V dual output

    TI Thinks Resolved
    Part Number: TPS7A78 Hello Team, can I set the LDO_in voltage to 15V and use as intermediate supply and the 5V as a low voltage output? My goal is to use the device as a supply for gate drivers. So I need 15V for the FETs and 5V logic level voltage. Thanks…
