ON / OFF pin driven by TTL (logic gate), open-collector bipolar transistor or open-drain MOSFET. How to calculate the max output current The internal power dissipation(PD)follows the equation: PD = Io x Vo x (1-) Io = PD / [ Vo x (1-)] Where PD = Internal power dissipation Io = Output current Vo = Output voltage = Efficiency Example: R-745.0P , at Vin = 28Vdc , Vo = 5Vdc ,=91% (see "Selection Guide" table) (a) When Ta = 60C , PD = 1.4 Watt (see beside diagram) Io = 1.4(W) / 5(V) x (1-0.91) = 3.11(A) (b) When Ta = 85C , PD = 1 Watt (see beside diagram) Io = 1(W) / 5(V) x (1-0.91) = 2.222(A) (c) At Vin = 12Vdc efficiency = 94% (see "Selection Guide" table) When Ta = 85C , PD = 1 Watt (see beside diagram) Io = 1(W) / 5(V) x (1-0.94) =3.33(A) www.recom-international.com REV: 2/2014 Ambient Temperature (C) Output Current vs Input Voltage 90 85 80 60 40 20 0 0.5 1 1.4 Internal Power Dissipation (W) I-53 R-7xxx Thermal Impedance 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 15 20 25 50 3.3V Ripple (mV) Ripple (mV) ( Vo ) 5 5V 50 Vo=3.3V ( Vo ) 28 5 10 Vin ( V ) 15 20 25 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 15 20 25 28 Vin ( V ) 80 ( Vo ) 70 1 3 2 Efficiency Vs Iout (Vin=Min) Efficiency (%) Efficiency (%) Efficiency (%) 50 60 ( Vo ) 4 1 3 2 Efficiency Vs Iout (Vin=Max) 4 R-7xxx Efficiency Vs Vin Package Style and Pinning (mm) SIP12 PIN Package 32.20 15.00 32.20 9.1 RECOM R-723.3P 0.7 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 2.54 Bottom View 2.13 0.7 0.2 2.54 0.2 Tolerance: 0.25 mm Bottom View 0.7 4.0 0.7 Pin Connections I-54 Pin # Name Description 1 ON / OFF 2, 3, 4 Vin Power input Input pin : Active low (less than 0.8V) to disable the device 5, 6, 7, 8 GND Input and output ground (common) 9 , 10, 11 Vout Power output 12 Vout-Adj With external resistors R1,R2 to selected output voltage REV: 2/2014 www.recom-power.com 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 8.5K 3.0 33K 470 3.2 110K 1.6K 7.0 560 13K 8.0 330 31K 10 2.2K 20K 11 390 47K 13 2.4K 36K 14 390 76K 3.3 R2 R1 R2 2.2K 3.4 36K 3.0K 3.6 11K 4.7K 3.9 4.7K 8.5K 4.5 1.6K 30K 4.9 820 220K 5.0 680 5.1 560 28K 12K 5.5 190 2.6K 20K 11K 6.0 47K 6.5 R-7xxx 9.0 12 15 16 2.6K 17 860 18 Standard Application Circuit Vin OFF 1F (Optional) ON 2, 3, 4 C1 TTL 1 Q1 R-72XX R-73XX R-74XX 5, 6, 7,8 9, 10, 11 Vout R1 12 (Adjust down) R2 (Adjust up) C2 100F/10V (REQD) Protection diodes are required for high capacitive loads.
