Abstract
A circuit that stores characterized loss information for a buck converter and uses the characterized loss information instead of measurements involving output power dependent losses. The characterized loss information may include the characterized switching loss, the characterized ripple loss, etc. The circuit may then calculate the output power, efficiency, power dissipation, etc. without needing to measure the output current.
