    LUME1 FW3X
    FOR FW3A/C/T CONSTANT CURRENT BUCK BOOST + FET DRIVER WITH ANDURIL

    Description:
    The LUME1-FW3X is a high efficiency constant-current buck-boost LED driver with direct-drive FET and was designed specifically as a driver upgrade for the FW3X family of flashlights. The LUME1 driver improves on the stock FW3X driver with significantly higher efficiency and run-time. The LUME1 driver also adds additional features such as auxiliary RGB LED support and improved temperature sensing.

    The LUME1 driver employs a synchronous 4-switch buck-boost architecture with automatic transition between buck and boost modes. Unlike conventional linear flashlight drivers which regulate current through linear pass-elements and modulate brightness via PWM, the LUME1 driver achieves significantly higher efficiency with its switching topology, eliminates PWM flickering, and maintains a true regulated output across the entire battery voltage range.

    As an e-switch driver that is always on, the LUME1 driver is also designed with a low 30µA standby quiescent current for excellent standby duration. The LUME1 driver is designed to support open-source firmware including Anduril.

    The LUME1 driver was developed by loneoceans from BudgetLightForum, together with the support and suggestions from the BLF community. More details can be found here: https://github.com/loneoceans/lume1-fw3x-anduril
