The LXM1614 series of Direct Drive™ CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules is specifically designed for driving LCD backlight lamps. Although similar to the RangeMAX LXM1612 wide range dimming inverters, the LXM1614 family offers two separate brightness controls for lamp current amplitude and duty cycle. This innovation of dual brightness control with extended dimming, combined with Linfinity’s high efficiency Direct Drive topology, provides the industry’s most feature rich, small form factor inverter available. The wide range dimming provides exceptional display readability at less than 1% of full brightness, allowing both power savings and low ambient light operating capability.
The LXM1614-14-11 is a dual‑drive, RangeMAX wide‑range dimming CCFL inverter designed for LCD backlight lamps. It offers independent brightness controls for lamp current amplitude and duty‑cycle, a boost mode for rapid warm‑up, and on‑board thermistor protection. The module operates from 9 V to 16 V input and can deliver up to 1800 V to the lamp.
Typical applications include automotive navigation displays, aircraft cabin displays, industrial notebooks, and other LCD backlight systems that require low‑ambient‑light operation or extended temperature ranges. The datasheet includes electrical characteristics, pin descriptions, mechanical dimensions, and recommended operating conditions.
