APPLICATION NOTES
1. Requirement on output load
Toꢀensureꢀthisꢀmoduleꢀcanꢀoperateꢀefficientlyꢀandꢀreliably,ꢀtheꢀminimumꢀoutputꢀloadꢀcannotꢀbeꢀlessꢀthanꢀ5%ꢀofꢀtheꢀfullꢀloadꢀduringꢀ
operation. If the actual output power is small, please connect a resistor at the output end in parallel to increase the load.
2. Recommended circuit
This series has been tested according to the following recommended testing circuit before leaving the factory. This series should be
testedꢀunderꢀloadꢀ(seeꢀFigureꢀ3).ꢀIfꢀyouꢀwantꢀtoꢀfurtherꢀdecreaseꢀtheꢀinput/outputꢀripple,ꢀyouꢀcanꢀincreaseꢀcapacitanceꢀproperlyꢀorꢀ
choose capacitors with low ESR (see table 3). However, the capacitance must not exceed the maximum capacitive load or a start-up
problem might arise (see table 4).

Notes:
ꢀ
1. Minimum load shouldn't be less than 5%, otherwise ripple may increase dramatically. Operation under minimum load will not damage the converter, however, they may
notꢀmeetꢀallꢀspecificationsꢀlisted.
2. Maximum capacitive load is tested at input voltage range and full load.
