L1: Coil for boost. The recommended value is 22µH. be sure to use a sufficient DC current permissible value and a  
sufficient low DC resistance coil.

Model number/manufacturer  
NR3015T220M / TAIYO YUDEN  
CIN: Bypass capacitor of power supply. This capacitor must be provided to remove an instantaneous power supply noise for  
stable voltage supply to this IC. To obtain good characteristics, the low ESR parts like the ceramics capacitor must be  
used. The recommended capacitance is 1µF or more.

When selecting capacitors for CIN and COUT, special care should be taken for rated voltage. The desirable rated  
voltage is about double the voltage actually applied to the capacitor. When the margin for rated voltage is not sufficient,  
the capacitance may be a half or less of the nominal value.  
D1: Schottky barrier diode (SBD) for output rectification. To achieve high conversion efficiency, use a diode characterized  
by of low Vf, low reverse leak and high current capacity.  
<Recommended parts>  
Model number/manufacturer  
RB160M-40 / ROHM  
●Recommended PCB layout  
When a PCB designed, the power supply line should be wired in a way that the board impedance can be minimized. If  
necessary, the bypass capacitor must be connected. In particular, pins around the DC/DC converter must be wired in such  
a way that the wiring impedance can be minimized. In addition, when a DC/DC converter using a coil is used, it is  
necessary to place the output capacitor COUT, coil L1, rectification diode D1 and bypass capacitor CIN near this IC and  
keep the GND impedance low.
