MIC3263 - Six-Channel WLED Driver for Backlighting Applications

Description

The MIC3263 is a high-efficiency Pulse Width Modulation (PWM) boost switching regulator that is optimized for constant-current WLED driver backlighting applications.

The MIC3263 drives six channels of up to ten WLEDs per channel.

Features

  • 6V to 40V wide input voltage range Drives 6 channels of up to 10 white LEDs Programmable WLED current from 15mA to 30mA Highly reliable operation with open and short LEDs Accurate 16 dimming log levels sets the dimming ratio from 1% to 100% Flicker-Free Dimming filters the jitter from the dimming control input signal and eliminates dimmin.

MIC3263 www.DataSheet4U.com Six-Channel WLED Driver for Backlighting Applications with Flicker-Free Dimming General Description The MIC3263 is a high-efficiency Pulse Width Modulation (PWM) boost switching regulator that is optimized for constant-current WLED driver backlighting applications. The MIC3263 drives six channels of up to ten WLEDs per channel. Each channel is matched in current to within ±3% for constant brightness across the screen and can be programmed from 15mA to 30mA. The MIC3263 provides a very flexible dimming control scheme with better accuracy and noise immunity. The dimming frequency can be set to any value between 100Hz and 20kHz by an external resistor.
