Io = P
Where
Example: R-745.0P , at Vin = 28Vdc , Vo = 5Vdc ,η=91% (see "Selection Guide" table)

Output Current vs Input Voltage
D
(a) When Ta = 60°C , P
(b) When Ta = 85°C , P
(c) At Vin = 12Vdc efficiency = 94% (see "Selection Guide" table)
= Io × Vo × (1-η)
D
/ Vo × (1-η)
P
Io = Output current
Vo = Output voltage
η = Efficiency
Io = 1.4(W) / 5(V) × (1-0.91) = 3.11(A)
Io = 1(W) / 5(V) × (1-0.91) = 2.222(A)
When Ta = 85°C , P
Io = 1(W) / 5(V) × (1-0.94) =3.33(A)
D
= Internal power dissipation
1. Requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications (the capacitor to be placed as close as possible to the output pins).
2. ON / OFF pin driven by TTL (logic gate), open-collector bipolar transistor or open-drain MOSFET.
