Precautions for using the module
(1) The module belongs to the step-down type module, the input voltage needs to be greater than the output of more than 1V to stabilize the output.
(2) The heating of the module is mainly determined by the input and output voltage difference and the load current. Please choose and use the power module reasonably. Generally, you need to reserve 30% of the surplus.
(3) The module generates heat during use, please purchasers to enhance heat dissipation according to the actual situation, when there is a large load; heat sinks, air cooling, etc. can be added appropriately.
(4) When using capacitive or inductive loads, the instantaneous current of the load cannot be too large, otherwise the module may be damaged.
Frequently asked questions
Q: Why the output voltage of the module cannot be greater than the input voltage?
A: The module is a step-down module and cannot be boosted; the maximum output voltage will be less than the input voltage of about 0.3V.
