TEL: +886-3-579-0068, FAX: +886-3-579-7534, E-mail: info@mblock..tw -1October 2011, V2.00 Product Description PWM-Embedded 3x4-Channel Constant-Current Sink Driver for LED Strips MBI6024 is a 3x4-channel, constant-current, PWM-embedded sink driver for LED strips. MBI6024 provides constant current ranging from 3m A to 45m A for each output channel and are adjustable with three corresponding external resistors. Besides, MBI6024 can support both 3.3V and 5V power systems and sustain 17V at output channels. With Scrambled-PWM (S-PWM) technology, MBI6024 enhances pulse width modulation by scrambling the “on” time into several “on” periods to increase visual refresh rate at the same gray scale performance. Besides, the gray scale clock (GCLK) is generated by the embedded oscillator. Moreover, MBI6024 provides...
