The LXMG1626-05-45 is a 5V Dual 6W CCFL (Cold Cathode Fluorescent Lamp) Inverter Module specifically designed to be compatible with variety of LCD panels that have both lamps on one side of the panel and use a single common lamp return wire. LXMG1626 modules provide the designer with a vastly superior display brightness range. This brightness range is achievable with virtually any LCD display. The modules are available with a dimming input that permits brightness control from either, a DC voltage source, a PWM signal or external potentiometer. The maximum output current is externally programmable (through the input connector) at either 10mA or 12mA (5mA or 6mA per lamp). This allows the inverter to match the panel’s lamp current specifications, or it can be used to purposely drive the lamps at a lower or higher current to decrease or increase nominal brightness. The inverter also has a dedicated FAULT pin that indicates an open/shorted lamp condition. In addition when only one of the two lamps in the LCD fails open, the second lamp will continue to operate with a FAULT signal toggling to indicate the failed condition, StayLit™feature. RangeMAX Digital Dimming Technology provides smooth dimming control.
The LXMG1626-05-45 is a dual‑6 W CCFL inverter module designed for LCD panels that share a common lamp return. It supports universal dimming inputs (PWM, voltage, or potentiometer) and provides programmable output current up to 12 mA per lamp. The module includes fault detection, open‑lamp continuation (StayLit™), and fixed‑frequency operation.
Key features include a wide dimming range (1 %‑100 %), flicker‑free burst drive, and protection against open/shorted lamps. Electrical specifications, pin descriptions, and typical application circuits are detailed in the following pages.
| Operating Ambient Temperature Range | -20 °C – 70 °C |
|---|---|
| Maximum Output Current (Open) | 12 mA |
The module can deliver up to 12 mA when the SET pin is left open, or up to 10 mA when the SET pin is tied to ground.
The FAULT pin is a high‑impedance output that goes high when a lamp is open or shorted, providing a fault indication.
Yes, the StayLit™ feature allows the remaining lamp to keep operating while the FAULT signal toggles to indicate the failure.
The module accepts PWM, a DC voltage (BRITE), or an external potentiometer for brightness control.
