COMMON SPECIFICATION APPLICATIONS The IF_RN-1W & IF_RT-1W Series are specially designed for applications where a group of polar power supplies are isolated from the input power supply in a distributed power supply system on a circuit board. 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 3000VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits.

IF_RN-1W&IF_RT-1W A/0-2008 Page 1 of 2 TYPICAL CHARACTERISTICS Temperature Derating Graph 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.

L L 22 0 C Vin Cin o +Vo DC DC (Figure 1) Cout GND 0V 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). 0.60 (0.024) OUTLINE DIMENSIONS & FOOTPRINT DETAILS First Angle Pr ojection 4.50 (0.177) 4.50 (0.177) IF_RN-1W Series 3.25 (0.602) S ide View IF_RT-1W Series 5.00 (0.197) 2.54 (0.010) 5.10 (0.201) 2.54 ( 0.010) EXTERNAL CAPACITOR TABLE (Table 1) Cin Vout Cout Vin (uF) (VDC) (VDC) (uF) 5 4.7 5 4.7 It's not recommended to connect any external capacitor in the application field with less than 0.5 watt output. 7.62 ( 0.300) 6.6 0 (0.260) 10.53 (0.415) 6.60 (0 .260) 12 14 567 8 19.50(0.768) 7.62 (0.300) B ottom View 12 14 567 8 Overload Protection Under normal operating conditions, the output circuit of these products has no protection against over load.
