MAX8751 Datasheet Full-bridge Ccfl Inverter Controller

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX8751 EVALUATION KIT AVAILABLE Fixed-Frequency, Full-Bridge CCFL Inverter Controller.

General Description

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.

This unique

Key Features

  • 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 adjusted with a resistor or synchronized to an external signal. The brightness is controlled by an analog voltage on the CNTL pin. The MAX8751 is capable of synchronizing and adjusting the phase of the ga.
