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: resistance value R = U 2 /(10 % ×2W );
Avoid excessively large output bypass capacitors: The external capacitor C2 at the output should not have an excessively large capacitance; otherwise, it may cause overcurrent during module startup or result in poor startup performance. Specifically, Selection should be based on the external capacitance meter.
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:
