DESIGN CONSIDERATIONS ) Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the minimum output load could not be less than 0% 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. ) Recommended circuit All the VRB_D-40W series have been tested according to the following recommended testing circuit before leaving factory. This series should be tested under load. Never be tested under no load (see Figure 3). If you want to further decrease the output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance can t exceed the maximum capacitor load in the list (Table ). 3) Cannot use in parallel and hot swap Cin (Figure 3) ut EXTERNAL CAPACITOR TABLE (TABLE ) Capacitance Output Cout(µF) Cin(µF) Voltage 3.3V, 5V 0 V, 5V 4V 47. Operation under minimum load will not damage the converter; However, they may not meet all specification listed.. Max. Capacitive Load tested at input voltage range and full load. 3. All specifications measured at Ta=5 C, humidity<%, nominal input voltage and rated output load unless otherwise specified. 4. In this datasheet, all the test methods of indications are based on our corporate standards. 5. All characteristics are for listed model only, non-standard models may perform differently, please contact our technical person for more detail. 6. Contact us for your specific requirement. 7.
