The coil is the part that is most influential to efficiency. Select the coil whose direct current resistor (DCR) and current -
inductance characteristic is excellent. BD6066GU/EKN are designed for the inductance value of 4.7μH or 6.8μH. Do not use
other inductance value. Select a capacitor of ceramic type with excellent frequency and temperature characteristics.
Further, select Capacitor to be used with small direct current resistance, and pay sufficient attention to the PCB layout shown
in the next page.
