Introduction
This documentation package covers two NCL30083 LED
driver implementations illustrating their use in an E26/E27
based A, PAR and BR LED lamps form factor. The
Electronic Circuit Assembly (ECA) is designed to support
either an isolated flyback or non-isolated buck-boost
configuration. The nominal total power is 10 W for either
application. The selection is controlled through selective
component population of the ECA.
