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.
FEATURES
Low cost and simple application circuit
High efficiency
Constant average power control
Low noise 35kHz constant frequency switching
Compact SOT-89 package
