LYTSwitch-2 Series AC / DC LED Driver ICs:

LYTSwitch-2 dramatically simplifies low power CC LED drivers by eliminating the optocoupler and secondary control circuitry. The family introduces a revolutionary control technique to provide very tight output current regulation, compensating for transformer and external component variations, and device parameter tolerances as well as input voltage variations.

• Controller Automatically Compensates For: Transformer inductance variation
