Figure 28. Basic Step-Up Switching Regulator
Figure 29. Relation of Switch Timing to Inductor Current in Step-Up Regulator
(16)
Since
ΔIL+ = ΔIL−, VINtON = VotOFF − VINtOFF,
and neglecting VSAT and VD1
(17)
The above equation shows the relationship between VIN, Vo and duty cycle.
In calculating input current IIN(DC), which equals the inductor's DC current, assume first 100% efficiency:
(18)
for
η = 100%, POUT = PIN
(19)
This equation shows that the input, or inductor, current is larger than the output current by the factor (1 +
tON/tOFF). Since this factor is the same as the relation between Vo and VIN, IIN(DC) can also be expressed as:
