Desktop Power [Adjustable Power Supply] [Krypton Upgraded Version]

Based on this project modification, the defects such as package confusion, silk screen masking, high current routing, BOM matching, etc. have been improved.
Update: The original author has released a mini version, welcome to watch.
 
Previous situation:
        I saw the original author's project on the homepage, which is very cost-effective, but was discouraged by the appearance (blame the mushroom). At the same time, some packages of the original project are mixed in honey, which is inconvenient to place an order. So when making this thing, the main consideration is the appearance and the degree of reproduction, and the cost is second [Krypton Gold Upgrade]. I have linked the number of LiChuang for everything that can be bought on LiChuang, so that everyone can sign in happily, secretly get coupons for free, and buy from LiChuang Mall for one point to get back the cost-effectiveness.
 
First, the picture:
Rendering effect:
1.0 Finished
 
 
desktop adjustable power supply, maximum 65V 4A output.
Supports external voltage meter.
The input part supports 24V terminal and PD fast charging 16V automatic deception
USB anti-backflow, 3A fuse protection
4P terminal output convenient wiring
 
application scenario:
electronic DIY
motherboard/notebook/mobile phone repair
high-power equipment test
electric race module
outdoor battery use
 
circuit part has not been greatly modified, step-down XL4015, step-up XL6019, two parts are independently connected in parallel. Fast charging deception uses Qinheng's chip, and the potentiometers are all on the same side for easy voltage adjustment. Use large-area copper plating for heat dissipation, and high power stability with heat sink.
 
Specific parameters:
Voltage input range: 4 ~ 37 V
Output voltage range: 1.25 ~ 60 V
Maximum current per channel: 4 A
Type-C input maximum current: 5 A (Please use 2P terminal for high power input, pay attention to heat)
Type-C loop fuse fuse current: 6 A
Input terminal: Type-C or 2P fence terminal
Output terminal: 4P fence terminal * 2 (boost/buck output separately)
 
Support external three-wire voltmeter
Boost part line sequence: Buck part line sequence:  
 
 
 
Assembly: This is actually optional. Use silicone thermal conductive glue to stick the heat sink on the back (Figure 2), then put the two pieces together and connect them with copper pillars. For high power, you can also put a fan underneath.
The cable can be fixed with a crimping terminal (cold-pressed terminal), which is more beautiful.

The two parts of the GND loop are completely connected, which will not affect the DIY power supply, but be careful when using it in other occasions. GPL 3.0 agreement, all commercial use is prohibited. I made it in my spare time when leading a club in the second year of high school. I am not very knowledgeable, so I hope you can give me some advice.
