FEATURES l Small Footprint l SIP/DIP Package l 3KVDC Isolation l Temperature Range: -40°C to +85°C 1W, FIXED INPUT, ISOLATED & REGULATED l No Heat sink Required l Internal SMD Construction SINGLE OUTPUT DC-DC CONVERTER l No External Component Required l Industry Standard Pinout l RoHS Compliance IF_S-1W & IF_D-1W Series APPLICATIONS The IF_S-1W & IF_D-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 demanded.

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. 2)Recommended circuit If you want to further decrease the input/output ripple, an “LC ” filtering network may be connected to the input and output ends of the DC/DC converter, see (Figure 1). L Vin Cin GND L +Vo DC DC Cout 0V (Figure 1) 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).

The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. 4)Input Over-voltage Protection Circuit The simplest device for inpu.
