  • TPS562209: power consumption at no load

    Resolved
    Part Number: TPS562209 Other Parts Discussed in Thread: TPS562201 Team, we observed a high power consumption of the converter (12mA) at no load (Vout=4V; Vin=7V). We'd expect max 1mA. Can you advise if the schematic is fine? We can take into account…
