Note:
1. C1 and C2 are required and should be connected close to the pin terminal
of the module.
2. The capacitance of C1 and C2 refer to Sheet 1, it can be increased properly
if required, and tantalum or low ESR electrolytic capacitors may also
suce.
3. When the products used as the circuit like gure 3, an inductor named as
LDM up to 10μH is recommended in the circuit to reduce the mutual
interference.
4. Cannot be used in parallel for output and hot swap.
5. Operation under no load will not damage these devices, however they may
not meet all specications. In order to ensure the converter can work
reliably with high eciency, please parallel a resistor on the output side
(The sum of the ecient power and resistor consumption power is not less
than 10%).
