A Wide-Input-Range Efficiency-Enhanced Synchronous Integrated LED Driver With Adaptive Resonant Timing Control.

A wide-input-range DC-DC-based dimmable LED driver is presented in this paper. The proposed LED driver can be automatically configured to operate in the soft-switching mode under the high-voltage condition in order to minimize the converter's dominant switching power loss. Adaptive resonant timing control is developed to enable proper dead-time generation for on-chip high-voltage power FETs in bot...
