LM3508 - Synchronous Magnetic Constant Current White LED Driver
The LM3508 is a synchronous boost converter (no external Schottky diode required) that provides a constant current output.
It is designed to drive up to 4 series white LEDs at 30mA from a single-cell Li-Ion battery.
A single low power external resistor is used to set the maximum LED current.
