LM3508 同步磁力恒流白光LED驱动 Pdf资料

应用功能：同步磁力恒流白光LED驱动 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.
