LM2596 3A STEP DOWN MODULE

LM2596 3A step-down module is a DC to DC buck converter step-down power module with a high precision potentiometer. LM2596 is an easy-to-use, nonsynchronous, step-down DC-DC converter with a wide input voltage range up to 35 V. It is capable of driving a load up to 3A with high efficiency. But heat sinks are used in a certain case when the output current required is greater than 2.5(or output greater than 10W). LM2596 3A step-down module takes the higher input and converts it into lower output voltage, thus provides excellent line and load regulation.

LM2596 is a monolithic integrated circuit with a series of regulators that perform all functions for a step-down switching regulator. These devices are available in fixed output voltages of 3.3V, 5V, 12V, adjusted by the high précised potentiometer. LM2596 step-down regulator modules operate at a switching frequency of 150 kHz thus allows small-sized filter components that require lower frequency. This module includes internal frequency compensation and a fixed-frequency oscillator. As a result, minimize external components and simplify power supply design.  LM2596 provides a switch-mode power supply function with high efficiency compared to the popular three-terminal linear regulators, especially with higher input voltages. This module works with  Freeduino UNO, other mainboards, and basic modules . Moreover, this module features thermal shutdown, current limit protection and internal loop compensation makes it suitable for wide range of application.
