Dual flash LED driver system featuring I²C dimming control and a 1.2A output current per channel. This boost topology IC operates from a 2.7V to 5.5V input and delivers up to 18.9V output. Integrated over-voltage protection (OVP) enhances reliability. The component is surface mountable in a 12-WSON package, measuring 3mm x 3mm x 0.8mm, and operates within a temperature range of -30°C to 85°C.
