Description for the LM3447-A19-230VEVM
The Texas Instruments LM3447-A19-230VEVM evaluation module (EVM) helps designers evaluate the performance of the LM3447 PFC Flyback Controller for LED Lighting. The EVM is a primary-side power regulated PFC controller used for commercial and residential phase-cut dimmer compatible LED lamp drivers. It uses fixed frequency valley switching operation, resulting in discontinuous current operation.
