These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation 5%); 2) Where isolation is necessary between input and output (isolation voltage 1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

L L Vin Cin +Vo Cout DC DC (Figure 1) GND L Co ut 0V -Vo It should also be noted that the inductance and the frequency of the "LC" filtering network should be staggered with the DC/DC frequency to avoid mutual interference. 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).

OUTLINE DIMENSIONS & PIN CONNECTIONS Overload Protection Under normal operating conditions, the output circuit of these products has no protection against over-current and short-circuits. The simplest First Angle Projection RECOMMENDED FOOTPRINT Top view,grid:2.54mm(0.1inch) diameter:1.00mm(0.039inch) method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. Input Over-voltage Protection Circuit The simplest device for input over-voltage protection is a linear voltage regulator with overheat protection that is connected to the input end in series (Figure 2). 31.80(1.252) 2.53 (0.100) 9.50 (0.374) (0.799) (0.600) 123 10 11 12 24 23 22 15 14 13 (Bottom View) 24 2322 1514 123 10 11 12 2.00 (0.079) 4.10 FOOTPRINT DETAILS Pin 1,24 2,23 3,10,15,22 11,14 12,13 Duals Vin -Vo 0V +Vo GND Vin GND REG +Vout DC DC (Figure 2) 0V -Vout Note: Unit:mm(inch) Pin diameter:0.50mm (0.020inch) Pin diameter tolerances: 0.10mm( 0.004inch) General tolerances: 0.25mm( 0.010inch) When the environment temperature is higher than 71C, the product output power should be less then 60% of the rated power. APPLICATION NOTE Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the minimum output load is not less than 10% of the full load, and that this product should never be operated under no load! If the actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our company's products with a lower rated output power. No parallel connection or plug and play. MORNSUN reserves the copyright Specifications subject to change without notice. IA_KP-*W A/1-2008 Page 2 of 2 |
