MAX8759ETI+

General Description
The MAX8759 integrated cold-cathode fluorescent lamp (CCFL) inverter controller is designed to drive CCFLs using a full-bridge resonant inverter.
The resonant operation ensures reliable striking and provides near-sinusoidal waveforms over the entire input range.
The controller operates over a wide input-voltage range of 4.5V to 28V with high power to light efficiency.
The device also includes safety features that effectively protect against single-point fault conditions such as lamp-out, secondary overvoltage, and secondary short-circuit faults.
