LTC3524 Datasheet Adjustable Tft Bias Supply

Manufacturer: Linear Technology Corporation

General Description

The LTC®3524 is an integrated BIAS and white LED power converter solution for small/medium-sized polysilicon thin film transistor (TFT) liquid crystal (LCD) display panels.

The device operates from a single Lithium-Ion/polymer battery or any voltage source between 2.5V and 6V.

A 1.5MHz synchronous boost converter generates a programmable low noise, high efficiency 25mA TFT supply of up to 6.0V.

Key Features

  • Generates Three Adjustable, Low Noise Rails for Small/Medium TFT Displays.
  • Drives Up to Ten White LEDs.
  • LED Dimming and Open-Circuit Protection.
  • Controlled Power-Up/Power-Down Sequencing.
  • 1.5MHz Fixed Frequency, Low Noise Operation www. DataSheet4U. com.
  • V Range 2.5V to 6V, V IN OUT Range 3V to 6V.
  • TFT Supply Efficiency Up to 90%.
  • LED Supply Efficiency Up to 78%.
  • Two Independantly Enabled LED Strings.
  • 200 to 1 True Color PWMTM Dimming.
  • Tiny External.
