Description
- LM3639AYFQEVM, Evaluation Board of the LM3639A Single-chip white LED Camera Flash Driver + LCD Display Backlight Driver. The low-voltage, high-current flash LED driver is a synchronous boost which provides the power for a single flash LED at up to 1.5A or dual LEDs at up to 750 mA each. The high-voltage backlight driver is a dual-output asynchronous boost which powers dual LED strings at up to 40V and 30 mA per string. An adaptive regulation method in both boost converters regulates the headroom voltage across the respective source/sink to ensure the LED current remains in regulation while maximizing efficiency
