Features:

1. Adopt new imported chips.

2. The maximum output current is 3A, running 2.1A for a long time, and the surplus is sufficient. 3A runs for about 20 seconds and the chip enters the overheat protection and restarts. It can work at 3A current by cooling and cooling the chip.

3. Using a new design scheme, the circuit design does not need electrolytic capacitors and tantalum capacitors (electrolytic capacitors have short life, tantalum capacitors are in danger of explosion). Three large-size solid-state ceramic capacitors (MCC) are used in high-end circuits.

This is a 20W adjustable DC-DC buck converter module with digital display. It is based on LM2596 3A step-down voltage regulator and supports an input of 4~40V DC with an accuracy of ± 0.05V.
