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 voltage =1500VDC); 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 Vout DC DC 0V GND 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) Extemal Capacitor Table(Table 1) Vout 5V 9V 12V 15V 3.3μF Cout/μF（max） 1000 680 470 220 2200 TYPICAL CHARECTERISTICS Temperature Derating Graph External Capacitor Operating Temp.( C ) FOOTPRINT DETAILS Top View Pin 23,24 1,2 13 15 Others Although this series of DC/DC converter can work without external capacitor, in order to keep an optimum performance, however, it needs external capacitor.

Input current of power supply should afford the startup current of this kind of DC/DC module (Figure 2) Input Current(A) OUTLINE DIMENSIONS (1.27) 10.5 15 14 13 16.1(0.63) (0.74) 24 23 22 Ip 123 10 1112 18.8 14.4 2.18 (0.085) 17.78 (0.7) 0.5 (0.02) 0.27 Input Voltage Range Input Voltage (V) (Top View) (Side View) Note: Unit: mm(inch); Tolerance: ±0.25mm; All Pins on a 2.54mm pitch; APPLICATION NOTE Requirement on Output Load To ensure this module operate efficiently and reliably, a minimum load is specified for this kind of DC/DC converter in addition to a maximum load (namely full load). During operation, make sure the specified range of input voltage is not exceeded, the minimum out put load is not less than 10% Of the full load, If the actual load is less below the specified minimum load, the output ripple of this type of DC/DC converter may increase drastically. If the actual output power from the load in your circuit is very small, please connect a resistor with proper resistance at the output end to in parallel to increase the load, or use our company’s other products with a lower rated output power. The products cannot be used in parallel and in plug and play. MORNSUN reserves the copyright For any design change and upgrade, we will not make any prior notification A/1-2007 Page 2 of 2
