LM2596S DC-DC step-down power module BUCK 3A adjustable step-down module

Product Description

This is an LM2596 DC-DC buck converter step-down power module with high-precision potentiometer for adjusting output voltage, capable of driving a load up to 3A with high efficiency. When the output current required is greater than 2.5A (10W) an external heat sink is suggested.

Features:

• Conversion efficiency: Up to 92% (output voltage higher, the higher the efficiency)
• Switching Frequency: 150KHz
• Rectifier: Non-Synchronous Rectification 
• Module Properties: Non-isolated step-down module (buck)
• Short circuit protection: current limiting, since the recovery 
• Operating temperature: Industrial grade (-40  to +85 ) (output power 10W or less) 
• Full load temperature rise: 40 
• Load regulation: ± 0.5%
• Voltage regulation: ± 2.5%

Connection Ports:

IN + IN- input input positive and negative!
The positive output OUT + OUT- output negative
Input voltage range: 4.5V to 40V DC (Must be greater than the input voltage to output voltage higher than 1.5V. Can not boost)

Output Voltage Range: 1.25V to 35V DC voltage is continuously adjustable, high efficiency (maximum 92%) of the maximum output current of 3A.

Found 12V input, load regulation 5V 1A output current is lower than 1%

Note: 

This is a step-down module, the input voltage is higher than the required output voltage.

Output 2A or less long period of time without additional heat sink output current is greater than 2.5A (or output power greater than 10W) to work long hours please add heat sink

Specification:

• Input voltage:4-35V
• Output voltage:1.23-30V(Adjustable)
• Output current:Rated current is 2A,maximum 3A(Additional heatsink is required)
• Dimension:48*23*14mm(L*W*H)

 Package Included:

1pcs *LM2596 DC-DC adjustable power step-down module
