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 87% (full load).
