EM8609A
Transition Mode PFC Controller for LED Lighting
General Description
EM8609A is a voltage mode PFC controller
operating at transition mode.
This device provides protections of internal
soft start, over voltage protection, over current
protection and thermal shutdown. It can minimize
the external components counts, and makes the
design easy.
It also provides functions of low start up
current, disable function, under voltage lockout
and internal leading edge blanking of the current
sensing.
This part is available in SOP-8 package.

Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
θJA SOP-8 packages is 52°C /W on JEDEC 51-7 (4 layers,2S2P) thermal test board with 50mm2 copper area.
Devices are ESD sensitive. Handling precaution is recommended.
The device is not guaranteed to function outside its operating conditions.
