4A Buck Boost converter with display. LCD input and output voltage, output current output power; Input anti-reverse protection, reverse connection will not burn. It can be step-up and step-down, the output voltage 0.5-30V arbitrary regulation, limiting the current 0-4A arbitrary regulation. Output anti-intrusion, the battery charge without additional anti-reflux diodes, Button control output ON / OFF status, and you can set the power-on default is ON or OFF. Ascending and descending chip used as the main controller, external 60V 75A MOS tube as a switch, double 60V 5A SS56 Schottky rectification, 60V voltage value, superior to the market immature XL6009 / LM2577 program (a lot Device pressure value is not enough, MOS tube and Schottky diode pressure value must be greater than the input plus input voltage value); Output ripple small, LC filter;


  1. Input voltage range: DC 5.5-30V (when the input voltage is 5V, the boost and buck can be achieved, but the voltage and current measurement is inaccurate; under 4.7V, under-voltage protection will be activated)
  2. Output voltage range: DC 0.5-30V
  3. The Output current can stably work at 3A for a long time, when enhancing heat dissipation can reach 4A
  4. Output power: 35W (natural cooling), when enhancing heat dissipation can reach 50W
  5. Voltage display resolution: 0.05V
  6. Current display resolution: 0.005A
  7. Conversion rate: about 88%
  8. Soft start: Yes, (a large power load module may fail when it is started)
  9. Input reverse connection protection: yes
  10. Output stop the current from feeding back protection: yes
  11. Short circuit protection: yes
  12. Working frequency: 180KHZ
  13. Size: 66 * 48 * 21mm
  14. Mounting hole: 4mm in diameter

Package Including:
1x 4A Buck Boost converter with display

An internal link is any link from one page on your website to another page on your website. Both your users and search engines use links to find content on your website. Your users use links to navigate through your site and to find the content they want to find. Search engines also use links to navigate your site. They won’t find a page if there are no links to it. There are several types of internal links. In addition to links on your homepage, menu, post feed, etc, you can also add links within your content. We call those contextual links. Contextual links point your users to interesting and related content. Moreover, they allow search engines to find out what content on your site is related and to determine the value of that content. The more links an important page receives, the more important it will seem to search engines. Therefore, good internal links are crucial to your SEO.
