Multi-channel DC-DC step-down module

Project Introduction:
The 2596 DC power conversion module is a high-efficiency and reliable power module suitable for motor drives, etc. It can convert 7-30V input voltage to 5V, 3.3V, and adjustable voltage output. It adopts a DC-DC architecture, offering advantages such as low ripple and a maximum continuous load of 1500V.
Project Function:
This design is based on the LM2596 switching power supply chip; it features three step-down outputs: 12V-3.3V, 12V-5V, and 12V-ADJ.
Project Parameters:
1. Power Input: DC 7V-30V, input voltage 2V higher than output voltage.
2. Three Outputs: 3.3V, continuous load 1.5A, peak load 2A; 5.0V, continuous load 1.5A, peak load 2A; ADJ adjustable voltage output, continuous load 1.5A, peak load 2A.
3. Double-sided board design, aesthetically pleasing layout
. 4. Multiple pin headers for input and output for easy use.
