LM3565 Overview
The LM3565 is a 4 MHz fixed-frequency, current mode synchronous boost converter designed to drive two series flash LEDs at 930 mA. A high-voltage current source allows the LEDs to be terminated to the GND plane eliminating the need for an additional return trace back to the IC. A dedicated Strobe pin provides a direct interface to trigger the flash event, while an external Torch pin provides an additional method for...
