㪜㪣㪤㪐㪇㪇㫏 WHITE LED FLASHLIGHT DRIVER

䂓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 transformed

to a 35kHz constant current pulse, when the external inductor switched on and off in 35kHz. In a standard

application inductor is needed as external parts.
