The LM2596S adjustable down converter module is designed to change the output voltage in the range from 1.25 to 35 V. The module can be used as a power supply, a power source for devices, batteries, to power high-power LEDs, etc.
The module board is designed on the basis of the LM2596 microcircuit, a tuning resistor, solid-state (polymer) capacitors, and other auxiliary electronic components. The LM2596 microcircuit is a step-down pulsed voltage converter, which has 8 pins and is made in the TO-263 package. The presence of solid-state capacitors provides high-quality voltage conversion and increases the life of the converter. The maximum value of the load current without additional cooling is 2 A. If there is an output power that exceeds 10 W, a radiator must be installed. The heat sink is attached to the housing of the chip. After connecting additional cooling, the load current can reach up to 3 A, and the output power up to 15 W. The efficiency of the converter can be up to 92%.
The chip has protection against short circuit (short circuit) and overheating (triggered at 150 ° C). Also has an output current limitation.
The power source and load are connected to the converter board using 4 metallized holes:
IN +: input voltage 4.5 - 40 V
IN-: "land"
OUT +: output voltage 1.5 - 35 V
OUT-: common load wire
