TEL: +886-3-579-0068, FAX: +886-3-579-7534 E-mail: info@mblock.com.tw – 1 – August, 2015, VA.00 MBI6023 PWM-Embedded 3×4-Channel Constant-Current Sink Driver for LED Strips Product Description MBI6023 is a 3×4-channel, constant-current, PWM-embedded sink driver for LED strips. MBI6023 provides constant current ranging from 3mA to 45mA for each output channel and are adjustable with three corresponding external resistors. Besides, MBI6023 can support both 3.3V and 5V power systems and sustain 17V at output channels. With Scrambled-PWM (S-PWM) technology, MBI6023 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, MBI6023 provides two selectable gray scale modes to trade off between image quality and transmission: 16-bit gray scale mode and 10-bit gray scale mode. In addition, MBI6023 features a two-wire transmission interface to make cluster-to-cluster connection easier. To improve the transmission quality, MBI6023 provides phase-inverse output clock to eliminate the accumulation of signal pulse width distortion. – 2 – August 2015, VA.00 MBI6023 Pin Configuration PWM-Embedded 3×4-Channel Constant-Current Sink Driver for LED Strips OUTA3 OUTB3 OUTC3 VDD R-EXTC R-EXTB GND CKI SDI TEST1 TEST2 SDO CKO VDD2 R-EXTA R-EXTB R-EXTC VDD 1 2 3 4 5 6 7 8 9 10 11 12 24 OUTA0 23 OUTB0 22 OUTC0 21 OUTA1 20 OUTB1 19 OUTC1 18 OUTA2 17 OUTB2 16 OUTC2 15 OUTA3 14 OUTB3 13 OUTC3 MBI6023GP Top View OUTC2 OUTB2 OUTA2 OUTC1 OUTB1 OUTA1 24 23 22 21 20 19 1 18 2 17 3 Thermal 16 4 Pad 15 5 14 67 8 13 9 10 11 12 R-EXTA VDD2 CKO SDO TEST2 TEST1 SDI CKI GND OUTA0 OUTB0 OUTC0 MBI6023GFN Top View Terminal Description Pin GP GFN Name Description and function 1 10 GND Ground termi […]
