Introduction The LM2596S DC to DC Step-Down converter is a device that converts DC voltages from higher to lower voltages. It is ideal for reducing voltages to the required level. It is built around LM2596S chip which is a switch−mode power supply regulator, its efficiency is significantly higher in comparison to other popular linear regulators, especially with higher input voltages.
Specifications Operating input voltage 4.5V to 40VDC Operating output voltage 1.2V to 35V (adjustable) Output current 2A (constant load) Switching frequency 150kHz Low power standby mode 80µ Load regulation 0.5% Voltage regulation 2.5% Storage temperature range −65 to +150℃ Dimensions 45x20x15mm [1.8x0.8x0.6in] The LM2576 device has current limiting to prevent the switch current from exceeding safe values during an accidental overload on the output.
The schematic The LM2576 regulator is designed to minimize the number of external components. The module is built from a LM2576 voltage regulator, and a few passive parts. It contains two electrolytic capacitors, two tantalum capacitors, one resistor, inductor coil, high-speed switching (Schottky) diode and a precision potentiometer for adjusting the output voltage.
Connection example The following image is an example of how to connect the module with other devices:...
