LM3555 General Description

The LM3555 is a 2-MHz fixed-frequency, currentmode synchronous boost converter designed to drive either a single flash LED at 500 mA or two series flash LEDs at 400 mA. A high-voltage current source allows the LEDs to be terminated to the GND plane eliminating the need for an additional return trace.
