Avoid operating under no-load conditions whenever possible: 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 start-up performance. The specific value should be selected based on the capacitor’s datasheet.
The product does not support parallel operation for power boosting.
In applications with stringent ripple‑noise requirements, an external LC filter should be used. The resonant frequency of the LC filter must be significantly lower than the switching frequency of the DC/DC converter to prevent mutual interference that could increase output ripple or damage the module, as shown in the figure.
