These products apply to: 1) Where the voltage of the input power supply is wide range (voltage range: 2:1); 2) Where isolation is necessary between input and output (Isolation Voltage1500VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

This series should be tested under load(Figure 1). Vin Cin GND Vout DC DC 0V TYPICAL CHARECTERISTICS Temperature Derating Graph If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high(Table 1) External Capacitor Table(Table 1) Vin 5V&12V 24V&48V Cin 100uF 22uF Cout (0~70) 100uF (electrolytic capacitor) Cout (-40~85) 47uF (tantalum capacitor) Recommended Reflow Soldering Profil e Operating Temp.( C ) FOOTPRINT DETAILS 242 32 2 16151 4 3 1 P in 22,23 Fu ncti on Vin GND +Vo 0V NC (Top Vie w) 2,3 14 16 Input Current Nominal input voltage range.The input current of the power supply must be sufficient to the startup current (Ip) of the DC/DC module (Figure 2) Input Current(A) 123 9 101 1 2 1 Oth ers OUTLINE DIMENSIONS 32.5 [1.28] 27.9 [1.10] 8.0 [0.31] 7.5 [0.30] Ip Input Voltage Range 22.5min [0.886] 19.2 [0.75] 20.5 [0.81] 26.4 [1.04] (Top View) 1.5 [0.06] 19.7 [0.78] R1.5 [R0.06] Input Voltage (V) No parallel connection or plug and play. 0.3 [0.01] 2.5 [0.10] 1.5 [0.06] 0.15 Note: Unit: mm(inch); Tolerance: 0.25mm. APPLICATION NOTE Output Load In order to ensure the product operate efficiently and reliably, in addition to a max load (namely full load), a minimum load is specified for this kind of DC/DC converter. Make sure the specified range of input voltage is not exceeded, the minimum output load no less than 10% full load, If the actual load is less than the specified minimum load, the output ripple may increase sharply. If the actual output power is very small, please add an appropriate resistor as extra loading,or contact our company for other lower output power products.
