(*1) Select components appropriate to the usage conditions (ambient temperature, input & output voltage).
(*2) For the coil capacitance value, please refer to P.8 < External soft-start setting >.
<Coil current setting >
For stable operation by current feedback control, the XC9248 series is optimum when the peak-to-peak current (Ipk) in the coil
is set approximately between 0.5A to 1A. The Ipk value can be calculated by using the following equation:
Ipk[A] = (VIN－VOUT ) × VOUT / VIN / 0.5 / L[μH]
L : Coil Inductance
