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 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_S-1W / 1watt DC-DC converter / Regulated / Single output-3

APPLICATION NOTE 1)Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the minimum output load could not be less than 10% of the full 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. 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 (Figure 1) It should also be noted that the inductance and the frequency...
