D*CRIPTION
The GM6102B is a HVLED lighting regulator for 90Vac to 130Vac input range. It supports dynamic shunt switching for a 6-section LED string (VF = 48V to 54V each). The GM6102B achieves high efficiency, t*ical 85% to 88%. It also achieves high power factor, t*ical 0.93 to 0.96. The GM6102B is highly integrated. The entire driver circuit and the LED module can be mounted on a single board, greatly reduce the cost and size of the LED light bulb. The GM6102B also provides over-temperature, LED short and LED open protection. The GM6123B has integrated EZ dimming function. By toggling the wall switch, its output can be varied from 100% to 50%, 25%, and 13%. The GM6123B also supports triac dimming. The GM6102B and GM6123B are available in SO-8EP and SO-16EP packages. For lower current ripple ratio, we recommend SO-16-EP package version.

APPLICATIONS
E17, E27(A19) lamps
