Not only is the EN29A0QI suitable for powering noise sensitive loads, but it is a very efficient solution with excellent thermal performance. As can be seen from these typical efficiency vs. output current curves, the EN29A0QI has very flat efficiencies for output currents from about 5A up to the full output current of 10A. For an input voltage of 12V, and output voltages of 1.05V and 3.3V, the full-load efficiencies are 85% and 91% respectively, and the part does not require any thermal derating for an ambient temperature of 85°C.
