typ. 93.7% at 24V, 12A (Power Boost)
Average efficiency
*)
typ. 94.3% 25% at 2.5A, 25% at 5A,
25% at 7.5A. 25% at 10A
Power losses typ. 1.75W at no output load
typ. 6.8W at 24V, 5A
typ. 14.7W at 24V, 10A
typ. 19.5W at 24V, 12A
*) The average efficiency is an assumption for a typical application where the power supply is loaded with 25% of the nominal load for 25%
of the time, 50% of the nominal load for another 25% of the time, 75% of the nominal load for another 25% of the time and with 100%
of the nominal load for the rest of the time.
