WHITE LED FLASHLIGHT DRIVER
GENERAL DESCRIPTION
ELM900x is a CMOS IC designed for driving white LEDs by one or two dry cell as a power source. ELM900x can drive two series white LED by 1.5V-3.0V input voltage. ELM900x uses an external inductor as a voltage booster. ELM900x consists of an oscillator circuit and a driving transistor. The input DC power is tr...
