USING ATTENTIONS
Try to avoid no-load use: when the load power consumption is less than 20% of the rated output power of the module, it is recommended to connect a dummy load
to the output terminal or choose a module with a lower rated power. The dummy load (resistance) can be 10-20% of the rated power of the module, resistance
T
value=U2/(20%*1/2/3W)
The output external capacitor should not be too large: The output capacitor C2 should not be too large, otherwise it will easily cause overcurrent or poor startup
when the module starts. The specific selection should be based on the external capacitor table.
CTRL terminal: Normal output When floating or high resistance;the Modules will shutdown when high level input or GND input .
The current of CTRL terminal is 5-10mA ,no more than 20 mA, the module will be Permanent damaged.
It is recommended to connect external LC filter circuit if Ripple& nocise requirement is strictly, Resonant frequency of the filter should be much smaller than DC/DC
module's frequency, to Prevent the mutual interference and high ripple&noise or module's damage.below picture for reference
