Notes:
1. Requires an electrolytic or tantalum output capacitor for proper operation in all applications (the capacitor to be placed as close as possible to the output pins)
100µF for R-52xxPA/DA, R-53xxPA/DA and R-54xxPA/DA or 220µF for R-55xxPA/DA.
2. ON / OFF pin driven by TTL (logic gate), open-collector bipolar transistor or open-drain MOSFET.
3. Output Current vs. Input Voltage (see graph below).
Output Current vs Input Voltage
How to calculate 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-545.0P , at Vin = 18Vdc , Vo = 5Vdc ,η=93% (see "Selection Guide" table)
(a) When Ta = 60°C , PD = 1.4 Watt (see adjacent diagram)
Io = 1.4(W) / 5(V) × (1-0.93) = 4(A)
(b) When Ta = 85°C , PD = 1 Watt (see adjacent diagram)
Io = 1(W) / 5(V) × (1-0.93) = 2.857(A)
(c) At Vin = 12Vdc efficiency = 94% (see "Selection Guide" table)
When Ta = 85°C , PD = 1 Watt (see adjacent diagram)
Io = 1(W) / 5(V) × (1-0.94) =3.33(A)
