STLED25 Description
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 load. The device also includes soft-start control, inrush current limit, thermal shutdown and inductor peak current limit.
