Efficiency is the ratio between the consumed input and given output power. The emerged difference is called energy loss.

Causes of energy loss include:

    Ohmic losses by transformer and leads
    Switching losses of SMPS
    Inserted filters for EMC activities
    Losses by multi stage (eg PFC & current control of LED drivers)
    Losses by processing the IC

Ottima′s LED drivers have efficiency levels of up to 90% (full load).
