LM2596S-ADJ DC-DC Buck Converter 4.5-40V to 3-35V 3A Adjustable Step Down Module

LM2596S DC-DC Converter 3A Step Down Module The LM2596S step-down module is based on the monolithic integrated circuit family designed for 3 A continuous load current. It serves as a high-efficiency buck converter, taking a higher input DC voltage and converting it to a lower regulated output voltage using switch-mode technology with an internal 150 kHz oscillator. Thanks to its fixed-frequency switcher design, the module allows for smaller external inductors and capacitors compared to lower-frequency linear regulators. The module form factors typically include an adjustable output version, enabling versatile use across a range of output voltages. It’s ideal when space is constrained and efficiency is important. In its typical module form, this converter includes the LM2596S IC, mounting pad/board, potentiometer for adjustment (in adjustable versions), and input/output terminals. Provided the input is sufficiently above the output, and thermal/heat-sinking is considered, the module provides a compact, adjustable, efficient solution for many power-supply tasks. Features: • Capable of driving up to 3 A load current (in ideal conditions). • Wide input voltage range (e.g., 3.2-40 V in module form) for flexible operation. • Adjustable output voltage version available (approx. 1.2-35 V in module form). • High switching frequency (~150 kHz) for smaller external components. • Built-in protection features: e.g., short-circuit/current-limit, thermal shutdown in the IC version. • Low external-component count due to internal compensation and oscillator. Specifications: Input voltage: 3-40V Output voltage: 1.5-35V(Adjustable) Output current: Rated current is 2A, maximum 3A(Additional heatsink is required) Switching Frequency: 150KHz Operating temperature: Industrial grade (-40 to +85 ) Conversion efficiency: 92%(highest) Load Regulation: ± 0.5% Voltage Regulation: ± 0.5% Dynamic Response speed: 5% 200uS Dimension: 43.5 x 21 x 14mm(L x W x H) Applications: • On-board power supply modules for electronics projects. • Battery-powered system voltage regulation. • Step-down power for logic/microcontroller peripherals. • General purpose buck conversion for hobby/DIY electronics.

LM2596S-ADJ DC-DC Buck Converter 4.5-40V to 3-35V 3A Adjustable Step Down Module DC-DC Buck Converter Step Down Module LM2596 Power Supply is a step-down(buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version. The LM2596 series operates at a switching frequency of 150kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators. LM2596S-ADJ DC-DC Buck Converter 4.5-40V to 3-35V Adjustable Step Down Module This is an LM2596 DC-DC buck converter step-down power module with the high-precision potentiometer, capable of driving a load up to 3A with high efficiency, which can work with Freeduino UNO , other mainboards, and basic modules. When the output current keeps greater than 2.5A (or output power greater than 10W), please add a heat sink to it. This device is internally compensated to minimize the number of external components to simplify the power supply design. Since LM2596 converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages. The LM2596 operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.
