LED constant current control chip RM9003A
General Description ：
Features：
RM9003A is a one_stage LED constant Simpler peripheral circuit without
current driving control chip which
magnetic components
Compatible with silicon controlled dimmer Chips can be used in series or parallel
application.Output current stay a constant
application
in the range of 5m~100mA as once set by Chips and LED can be welded in the
external SENSE resistor.
same PCB board
It has the advantages of simpler system Output current can be set by external
structure fewer peripheral components
resistor
and simpler circuit.
