STLED25 Datasheet (STMicroelectronics) - 5 channels step-up white LED driver

STLED25, 5 channels step-up white LED driver

Flip-Chip 12 bumps (1.4 x 1.8 mm.) continue operating driver channels that are functioning normally, while avoiding excessive power consumption or associated thermal issues.

The control technique is able to maintain the efficiency close to 87% at medium load and higher than 85% at light or full loa
