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-745.0P , at Vin = 28Vdc , Vo = 5Vdc ,η=91% (see "Selection Guide" table) (a) When Ta = 60°C , PD = 1.4 Watt (see beside diagram) Io = 1.4(W) / 5(V) × (1-0.91) = 3.11(A) (b) When Ta = 85°C , PD = 1 Watt (see beside diagram) Io = 1(W) / 5(V) × (1-0.91) = 2.222(A) (c) At Vin = 12Vdc efficiency = 94% (see "Selection Guide" table) When Ta = 85°C , PD = 1 Watt (see beside diagram) Io = 1(W) / 5(V) × (1-0.94) =3.33(A) I-56 REV: 0/2015 Ambient Temperature (°C) R-7xxx Potting Material 90 85 80 60 40 20 0 0.5 1 1.4 Internal Power Dissipation (W) www.recom-power.com R-7xxxP_D Series INNOLINE DC/DC-Converter Characteristics R-72xx / R-73xx Ripple VS Vin R-72xx / R-73xx Efficiency VS Vin R-74xx Ripple VS Vin 50 100 Vo=15V Vo=12V Vo=6.5V Vo=9V Vo=5V 6.5V 10 20 15 25 3.3V Ripple (mV) Ripple (mV) ( Vo ) 5 5V 50 Vo=3.3V ( Vo ) 28 5 10 Vin ( V ) 15 20 25 50 Efficiency (%) 25 15V 6.5V 5V 3.3V 100 ( Vo ) 5 28 10 Vin ( V ) Ripple Vs Vin 28 R-72xx / R-73xx / R-74xx Efficiency / Load Vin=Max 100 Vo=6.5V Vo=5V Vo=3.3V 25 Efficiency Vs Vin R-72xx / R-73xx / R-74xx Efficiency / Load Vin=Min 100 20 Vin ( V ) Ripple Vs Vin R-74xx Efficiency VS Vin 15 100 6.5V 5.0V 3.3V 90 15V 5.0V 3.3V 90 80 ( Vo ) 5 10 20 15 25 28 80 ( Vo ) 70 Vin ( V ) 1 3 2 Efficiency Vs Iout (Vin=Min) Efficiency (%) Efficiency (%) Efficiency (%) 50 60 ( Vo ) 4 1 3 2 Efficiency Vs Iout (Vin=Max) 4 Efficiency Vs Vin R-7xxx Package Style and Pinning (mm) SIP12 PIN Package 32.20 RECOM R-723.3P 15.00 32.20 9.1 Front (Label) 0.7 Front (Label) MAX 17.00 1 2 3 4 5 6 7 8 9 10 11 12 4.0 2.13 RECOM R-723.3D 15.00 1 2 3 4 5 6 7 8 9 10 11 12 9.1 2.13 0.7 0.2 2.54 0.2 2.54 Bottom View Bottom View 0.7 4.0 0.7 Pin Connections Pin # Name 1 ON / OFF 2, 3, 4 Vin Power input 5, 6, 7, 8 GND Input and output ground (common) 9 , 10, 11 Vout Power output 12 Vout-Adj www.recom-power.com Description Input pin : Active low (less than 0.8V) to disable the device Tolerance: xx.x xx.xx ±0.5mm ±0.25mm With external resistors R1,R2 to selected output voltage REV: 0/2015 I-57 R-7xxxP_D Series INNOLINE DC/DC-Converter Table 1: Adjustment Resistor Values 2ADC R-723.3P/D R-725.0P/D R-726.5P/D R-729.0P/D R-7212P/D R-7215P/D 3ADC R-733.3P/D R-735.0P/D R-736.5P/D R-739.0P/D R-7312P/D R-7315P/D 4ADC R-743.3P/D R-745.0P/D R-746.5P/D Vout (nominal) 3.3Vdc 5.0Vdc 6.5Vdc 9.0Vdc 12Vdc 15Vdc Vout (adj) R1 R2 R1 R2 R1 R2 R1 R2 R1 2.5 8.5KΩ 3.0 33KΩ 470Ω 3.2 110KΩ 1.6KΩ 7.0 560Ω 13KΩ 8.0 330Ω 31KΩ 10 2.2KΩ 20KΩ 11 390Ω 47KΩ 13 2.4KΩ 36KΩ 14 390Ω 76KΩ 3.3 R2 R1 R2 2.2KΩ 3.4 36KΩ 3.0KΩ 3.6 11KΩ 4.7KΩ 3.9 4.7KΩ 8.5KΩ 4.5 1.6KΩ 30KΩ 4.9 820Ω 220KΩ 5.0 680Ω 5.1 560Ω 28KΩ 12KΩ 5.5 190Ω 2.6KΩ 20KΩ 11KΩ 6.0 47KΩ 6.5 R-7xxx 9.0 12 15 16 2.6KΩ 17 860Ω 18 Standard Application Circuit Vin OFF 1µF (Optional) ON TTL 2, 3, 4 C1 1 Q1 R-72XX R-73XX R-74XX 5, 6, 7,8 9, 10, 11 Vout R1 12 (Adjust down) R2 (Adjust up) C2 100µF (Required) Protection diodes are required for high capacitive loads.
