RM9003B Description
： RM9003B is a one_stage LED constant current driving control chip which patible with silicon controlled dimmer application.Output current stay a constant in the range of 5m~100mA as once set by external SENSE resistor. It has the advantages of simpler system structure fewer peripheral ponents and simpler circuit. Applications ： LED Fluorescent tube T5/T8/T10… LED Bulb/Corn light/Candle lamp… Other small power LED...
