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.

Features:

The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat and do not yield any current step up. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
