LM2596 2A step-down module is a DC to DC buck converter step-down power module with a high precision potentiometer. It also comes with a built-in voltmeter display and uses an advanced microcontroller.LM2596 is an easy-to-use, nonsynchronous, step-down DC-DC converter with a wide input voltage range up to 40 V. It is capable of driving a load up to 2A with high efficiency. This module takes the higher input and converts it into lower output voltage, thus provides excellent line and load regulation. Along with a high-precision multi-turn potentiometer, any desired output voltage within its range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 4 ~ 40V and an adjustable output range of 1.3 ~ 37V.
LM2596 designed as a monolithic integrated circuit with a series of regulators. It can 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 a wide range of applications.
