Fonctionnalités et applications

The MIC3263YML TR is a 20 V high-efficiency Pulse Width Modulation (PWM) boost switching regulator that is optimized for constant-current WLED driver back lighting applications

The MIC3263 drives six channels of up to ten WLEDs per channel. Each channel is matched in current to with in ±3% for constant brightness across the screen and can be programmed from 15 mA to 30 mA.

Features:

  • 6 V to 40 V wide input voltage range
  • Drives 6 channels of up to 10 white LEDS
  • Programmable WLED current from 15 mA to 30 mA
  • Highly reliable operation with open and short LEDs
  • Accurate 16 dimming log levels sets the dimming ratio from 1% to 100%
  • Allows external dimming control
  • Accurate LED channel Current matching ±3%
  • Accurate initial led current setting ±2%
  • Programmable switching frequency from 400 kHz to 1.8 MHz
  • High efficiency up to 90%
  • Over temperature protection
  • Programmable over-voltage protection
  • -40°C to +125°C junction temperature range

Applications:

  • White LED driver for backlighting
  • Notebooks
  • LCD Panels and Monitors
  • Multimedia players
  • Navigation equipment
