IML iML8683
iML8683
Three Terminal Current Controller
General Description
The iML8683 is a Three Terminal Current
Controller (TTCC) for regulating the current flowing
through an LED string.
The application of the iML8683 is configured in
parallel with an LED string. The iML8683 can work
as voltage controlled current source, current
regulator, or cut-off. It is suitable for the applications
adopting periodical AC voltage source.
The PCB layout is also very flexible to meet
various shape requirements. It is especially suitable
for replacing incandescent light bulb and linear type
fluorescent lamp.
Features
