Laptop charger

Overview

This is a classic boost converter circuit, providing a stable 20V output with a maximum output of 1.5A. A heatsink is required during use; avoid touching the heatsink while it is in operation. A 12V battery is recommended as the input power source; insufficient input voltage will cause the module to overheat. This circuit has been verified to function correctly.
