APPLICATION NOTE
1. Setting Operating Conditions
Setting output voltages
The output voltage can be set by adjusting the setting output voltage resistor ratio. Setting output voltage is
calculated by the following formula.
R1 + R2
2.8 10-7

VOUTx =
R2

VOUTx
: Output setting voltage [V]
VIN
: Power supply voltage [V]
ΔVOUTX : Output ripple voltage value [V]
tOFF
: Off time [s]
RON_Sync
: ON resistance of low-side FET [Ω]
ΔIL
: Ripple current peak-to-peak value of inductor [A]
ESR
: Series resistance element of output capacitor [Ω]
L
: Inductor value [H]
fOSC
: Switching frequency [Hz]
