The LM3565 is a 4 MHz fixed-frequency, current mode synchronous boost converter designed to drive two series flash LEDs at 930 mA. It features a high-voltage current source that allows LEDs to be terminated to the GND plane, an 8-bit ADC for monitoring LED and input voltage, and an I2C-compatible interface. The device includes hardware-enabled strobe and torch pins, along with a transmit interrupt pin to protect the battery during simultaneous high-current events.
