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. www.DataSheet4U.
