DC DC Step Down LM2596 Buck Converter 4.5-40V To 3-35V 3A Adjustable Module Power Supply This module features the adjustable LM2596 step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. This is an LM2596 DC-DC buck converter step-down power module with high-precision potentiometer, capable of driving a load up to 3A with high efficiency, which can work with Arduino 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 on it. The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for 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. Application includes Simple High-Efficiency Step-Down (Buck) Regulator, On-Card Switching Regulators, Positive to Negative Converter Features: Condition:100% Brand New with High Quality Compact size LM2596S converter IC Output voltage adjustment Uses Readily Available Standard Inductors High Efficiency Low Power Standby Mode, IQ TTL Shutdown Capability Adjustment method: first correct input power (between 4.5-50V) then multimeter to monitor the output voltage and adjust potentiometer (usually clockwise turn boost, buck turn counterclockwise), Input: IN+ input positive IN- input negative Output: OUT+ output positive OUT- output negative Static power consumption is only about 6mA. Connection: Welding, plus pin can be directly soldered after the PCB. Short circuit protection: current limiting, thermal protection, self-recovery. Non-isolated step-down (BUCK) switching regulator. Short circuit protection: Current limiting, self-recovery Potentiometer adjustment direction is as Clockwise (increase) and Anti-clockwise (decrease) Non-synchronous rectification Specifications: Module property: Non-isolation buck Rectification mode: Non-synchronous rectification Type: LM2596 Adjustable Power Supply Module Short Circuit Protection: Current limiting, since the recovery Input Voltage: DC 4V-35V Output Voltage: DC 1.23V-30V Output Current:3A (Maximum) Conversion Efficiency:92%(Highest) Output Ripple:30mv(Maximum) Switching Frequency:150KHz Load regulation:0.5% Voltage regulation:2.5% Work temperature:-40?- +85? Dimension: 43x20x14mm Quantity:1Pcs as A Set Instructions: 1. Power (3-40V), power indicator light, the module is working properly. 2. Adjust the blue potentiometer knob (clockwise rotation generally boost, counter-clockwise rotation Turn down) and reach with a multimeter to monitor the output voltage required voltage. Please make sure all of the “IN-” “IN+” “OUT-” “OUT+” marks are inserted Rightly, otherwise the module will be damaged. Package Included: 1 x DC DC Step Down LM2596 Buck Converter 4.5-40V To 3-35V 3A Adjustable Module Power Supply
