Figure 23. Relation of Switch Timing to Inductor Current in Step-Down Regulator
(4)
Neglecting VSAT, VD, and settling ΔIL
+ = ΔI
L
−;
(5)
where T = Total Period
The above shows the relation between VIN, Vo and duty cycle.
(6)
as Q1 only conducts during tON.
(7)
The efficiency,
η, of the circuit is:
(8)
ηMAX will be further decreased due to switching losses in Q1. For this reason Q1 should be selected to have the
maximum possible fT, which implies very fast rise and fall times.
Calculating Inductor L1
(9)
Since
ΔIL+ = ΔIL
− = 0.4I
o
Solving the above for L1
