MAX8729 Overview

Description

The MAX8729 cold-cathode-fluorescent lamp (CCFL) inverter controller is designed to drive multiple CCFLs using the half-bridge inverter consisting of two external n-channel power MOSFETs. The half-bridge topology minimizes the component count, while providing near sinusoidal drive waveforms.

Key Features

  • ensures reliable striking under all conditions and reduces the transformer stress
  • The MAX8729 provides accurate lamp-current regulation (±2.5%)
  • The lamp current is adjustable with an external resistor
  • The brightness can be adjusted with an analog voltage on the CNTL pin
