FEATURES l Small Footprint l SIP Package l 3KVDC Isolation l Temperature Range: -40°C to +85°C l No Heat sink Required l Internal SMD Construction l No External Component Required l Industry Standard Pinout l RoHS Compliance IF_S-2W Series 2W, FIXED INPUT, ISOLATED & REGULATED SINGLE OUTPUT DC-DC CONVERTER Patent Protection RoHS The IF_S-2W 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 / Single output-2

ISOLATION SPECIFICATIONS Item Test condition Isolation voltage Input-Output, tested for 1 minute and leakage current less than 1 mA Isolation resistance Isolation Capacitance TYPICAL CHARACTERISTICS Temperature Derating Graph OUTLINE DIMENSIONS & pIN CONNECTIONS 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....

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).
