L5109 - WHITE LED STEP-UP CONVERTER

Description

The UTC L5109 is an inductor-based DC/DC converter designed to drive up to six white LEDs in series or 2 rows of LEDs with 5 for each in parallel for backlight.

Only one feedback resistor is needed to control the LED current and obtain required brightness.

Features

  • S.
  • Inherently Uniform LED Current.
  • High Efficiency up to 83.5%.
  • No Need for External Schottky Diode.
  • Over Output Voltage Protection.
  • OVP.
  • 1.2MHz Switching Frequency.
