How to calculating the max output current
The internal power dissipation(P
D
)follows the equation:
P
D
= Io × Vo × (1-
η
)
Io = P
D
/ Vo × (1-
η
)
Where
P
D
= Internal power dissipation
Io = Output current
Vo = Output voltage
η
= Efficiency
Example: R-745.0P , at Vin = 28Vdc ,Vo = 5Vdc ,
η
=91% (see table 1)
(a) When Ta = 60°C , P
D
= 1.4 Watt (see fig-1)
Io = 1.4(W) / 5(V) × (1-0.91) = 3.11(A)
(b) When Ta = 85°C , P
D
= 1 Watt (see fig-1)
Io = 1(W) / 5(V) × (1-0.91) = 2.222(A)
(
c) At Vin = 12Vdc efficiency = 94% (see table 1)
When Ta = 85°C , P
D
= 1 Watt (see fig-1)
Io = 1(W) / 5(V) × (1-0.94) =3.33(A)
