LT3799 Datasheet (Linear Technology) - Offline Isolated Flyback LED Controller

LT3799, Offline Isolated Flyback LED Controller

The LT®3799 is an isolated flyback controller with power factor correction specifically designed for driving LEDs.

The controller operates using critical conduction mode allowing the use of a small transformer.

Using a novel current sensing scheme, the controller is able to deliver a well regulated
