The table of Fig. 4-52B lists the measured efficiency of circuits using the indicated coils. Efficiencies can be improved slightly by placing a Schottky diode (such as the 1N5817) in parallel with the intemal diode, from pin 4 to 5. The increase in efficiency is most noticeable for the 5-V output circuits.
