LM2596 DC-DC Buck Converter Adjustable Step Down Power Supply 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 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.

Technical Specification:

• Input Voltage: 3.2V ~ 40V
• Output Voltage: 1.25V ~ 35V(Adjustable)
• Output Current: ≤ 3A
• Conversion Efficiency: ≤ 92%
• Output Ripple: < 30mV
• Switching Frequency: 65KHz
• Working Temperature: -45℃~ +85℃
• Standard Size: 43.2mm x 21.0mm x 14.0mm (Length x Width x Height)

Features:

• Non-isolated step-down (BUCK) switching regulator
• Short circuit protection: Current limiting, self-recovery
• Potentiometer adjustment direction is as Clockwise (increase) and Ani-clockwise (decrease)
• Non-synchronous rectification

Applications:

• It can be applied to the vehicle regulated power supply
• To power the electronic equipment, when the equipment needs a 3 ~ 35V power supply, the voltage can be easily adjusted to the required voltage by using this module
• It can be used for system working voltage test. When doing the project, you can use this module to debug the working voltage range of various voltage test systems
