OUTPUT CURRENT vs INPUT VOLTAGE
How to calculating the max output current
The internal power dissipation(PD)follows the equation:
PD = Io × Vo × (1-η)
Io = PD / Vo × (1-η)
Where
PD = 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 ,PD = 1.4 Watt (see fig-1)
Io = 1.4(W) / 5(V) × (1-0.91) = 3.11(A)
(b) When Ta = 85°C ,PD = 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 ,PD = 1 Watt (see fig-1)
Io = 1(W) / 5(V) × (1-0.94) =3.33(A)
