TYPICAL CHARACTERISTICS DC If you want input/output to ripple, further you decrease can the increase capacitance properly or choose capacitors with low ESR. However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1).General: Cin: Operating Temp.( C ) OUTLINE DIMENSIONS & FOOTPRINT DETAILS (0.070) First Angle Projection (0.400) 13.70(0.539) 23.80(0.937) RECOMMENDED FOOTPRINT Top view,grid:2.54mm(0.1inch), diameter:1.00mm(0.039inch) 8 1 Single/ Dual Output Bottom view 16 10 9 16 3.01 (0.119) 15.24 (0.600) 10 12V 100μF 24V 10μF-47μF Cout: 10μF/100mA External Capacitor Table(Table 1) Single Vout Cout Dual Vout (VDC) (uF) (VDC) 3.3 2200 ±5 5 1000 ±9 9 680 ±12 12 470 ±15 15 330 - 100 Cout (uF) 680 470 330 220 - Input Current When it is used in unregulated power supply, 9 be sure that the fluctuating range of the power 7 8 1 supply and the rippled voltage do not exceed 2.54 (0.100) Note: Unit:mm(inch) Pin diameter:0.50mm(0.020inch) Pin diameter tolerances: 0.05mm( 0.002inch) General tolerances: 0.25mm( 0.010inch) supply should afford the startup current of this FOOTPRINT DETAILS Pin Single GND NC NC 7 8 9 +Vo 0V 10 Vin 16 NC:No Connection kind of DC/DC module (Figure 2) Dual General: Ip ≤1.4*Iin-max: GND NC 0V +Vo -Vo Vin Input Current(A) Side view 4.10 (0.161) 7.62 (0.300) the module standard. Input current of power Ip Input Voltage Range APPLICATION NOTE Input Voltage (V) Requirement on 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 No parallel connection or plug and play. 10% load. If the actual load is less than the specified minimum load, the output ripple may increase sharply while its efficiency and reliability will reduce greatly. 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.
