Product Introduction LM2596 is a step down power management monolithic integrated circuit switching voltage regulator capable of outputting 3A drive current while having good linearity and load regulation characteristics This module integrates 4 LM2596 which can output four sets of power supplies of 3 3V 5V 12V and ADJ at the same time The module is laid out and wired in strict accordance with the design specifications of the power supply circuit the materials are generous using SMD aluminum electrolytic capacitors high Q high power inductors In order to ensure the stable output voltage the window treatment on the back of the PCB board is more conducive to the heat dissipation of the LM2596 chip It is suitable for the power demand of students in learning competitions and company or personal project developmentPrecautions for using the module 1 The module is a step down module and the input voltage needs to be greater than the output 1Vto stabilize the output 2 Module heating is mainly determined by the input and output voltage difference and the load current Please select and use the power module reasonably Generally 30 of the margin should be reserved 3 The module generates heat during use please increase the heat dissipation according to the actual situation When carrying a large load you can add heat sinks air cooling etc appropriately 4 When using capacitive or inductive loads the instantaneous current of the load cannot be too large otherwise th
