Overview

MAX8729 EVALUATION KIT AVAILABLE Constant-Frequency, Half-Bridge CCFL Inverter Controller General 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.
The MAX8729 operates in resonant mode during striking and switches over to constant-frequency operation after all the lamps are lit.
This unique feature ensures reliable striking under all conditions and reduces the transformer stress.
The MAX8729 provides accurate lamp-current regulation (±2...
