Based on XL4016 high current 12V/9A-DCDC

 
1. Introduction
Based on XL4016 high current 12V/9A step-down board, both input and output use DC power socket inner diameter: 2.5mm outer diameter: 6.5mm, fixed 180KHz switching frequency, built-in output over-current protection, function. Low ripple, excellent linearity and load regulation characteristics.
 
2. Application Scenarios
 
LCD TVs and Displays
Portable Instruments Power
Supply Communication Equipment
 
3. Product Overview
 
The output voltage can be changed by changing R1 and R2. The calculation formula is
VOUT=1.25*(1+R2/R1)12V=1.25*(1+ 13K/1.5K)
 
4. Product parameters
 
Voltage input: 8V~36V
Conversion efficiency: 95%
 
5. Instructions for use
 
If you do not have professional equipment, you cannot conduct other tests such as ripple (neurological school).
You need to pay attention to the problem of large current heat dissipation. It is recommended to use heat dissipation chip and other cooling solutions.
There is no short circuit protection. Pay attention to the positive and negative poles during the test.
 
5.
There is no suitable heat sink in the actual picture, and it is not loaded in the actual shot.
