Avoid operating under no-load conditions whenever possible: When the load power consumption is less than the module’s rated output power of 10% , it is recommended to connect a dummy load at the output or to select one with a lower rated power. of the module, the dummy load (resistor) can be set to 10% of the module’s rated power. % Calculate the resistance value R = U 2 /(10 % ×1W );
Avoid excessively large output bypass capacitors: The external capacitor C2 at the output should not have an excessively large capacitance; otherwise, it may easily cause overcurrent during module startup or result in poor startup performance. Specifically, Selection should be based on the external capacitance meter.
This product series does not support hot-swapping on the input side or parallel operation on the output side.
For applications with stringent ripple noise requirements, an external LC filter should be connected. Filter circuit, L C The resonant frequency of the filter must be much lower than the DC/ DC The switching frequency of the module, Prevention To prevent mutual interference that could increase output ripple or damage the module, as shown in the figure:
