2021: Laj641p Schematic

Older LAJ641P schematics did not include USB-C. The 2021 revision (JUSB1) that multiplexes with the HDMI port.

The LAJ641P is a high-performance, high-frequency power MOSFET driver IC designed for high-power applications. It is commonly used in power supplies, motor control circuits, and audio equipment, where high efficiency and reliability are critical. The LAJ641P is known for its high current driving capability, fast switching speed, and low power consumption. laj641p schematic 2021
