TYPICAL CHARACTERISTICS The inductance and 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. RECOMMENDED REFLOW SOLDERING PROFILE 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 the 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. It's not recommended to connect any external capacitor in the application field with less than 0.5 watt output. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2382 |
