Description

The MAX8759ETI+TG05 is an integrated cold-cathode fluorescent lamp (CCFL) inverter controller designed to drive CCFLs using a full-bridge resonant inverter. It operates over a wide input-voltage range of 4.5V to 28V with high power to light efficiency. The device includes safety features that protect against single-point fault conditions such as lamp-out, secondary overvoltage, and secondary short-circuit faults.
