MAX8751, Full-Bridge CCFL Inverter Controller

The MAX8751 cold-cathode-fluorescent lamp (CCFL) inverter controller is designed to drive multiple CCFLs using the fixed-frequency, full-bridge inverter topology.

The MAX8751 operates in resonant mode during striking and switches over to constant-frequency operation after all the lamps are lit.

* that effectively protect against many single-point fault conditions, including lamp-out and short-circuit conditions. The MAX8751 achieves a 10:1 dimming range by “chopping” the lamp current on and off using the digital pulsewidth modulation (DPWM) method. The DPWM frequency can be accurately adjus
