AW9967 Overview
The boost converter runs at 1.1MHz fixed switching frequency, with an internal 40V, 2A switch FET, the AW9967 can drive one string (up to 10 LEDs) and parallel LED strings. n The full-scale WLED current can be set by the equation 200mV/RSET. RSET should be changed for e parallel applications.
