LV52204MT: LED Boost Driver with PWM and 1-Wire Dimming

The LV52204MT is a high voltage boost driver for LED drive. LED current is set by the external resistor R1 and LED dimming can be done by changing FB voltage with PWM or 1-Wire.

Features
  • Operating Voltage from 2.7V to 5.5V
  • Integrated 40V MOSFET
  • 1-Wire 32 level digital and PWM dimming
  • 600kHz Switching Frequency
Benefits
  • Wide operating input voltage range for hand held equipment
  • White LED can do series connection till 10 pcs.
  • The LED's current can do 32 phases adjustment
  • Small inductor is available
Applications
  • LED Display Backlight Control
