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. BD6583MUV-A is designed for the inductance value of 4.7µH. Don’t uses the
inductance value less than 2.2µH. 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
layout pattern shown in P.16.
