It is ideal for driving typical 12.1” to 15” panels. The maximum output current is externally programmable over a range of 5 to 8A in 1mA steps to allow the inverter to properly match to a wide array of LCD panel lamp current specifications. The modules are include a dimming input that permits brightness control from either a DC voltage source, a PWM signal or an external potentiometer. LXM1618 modules unlike the LXM1617 series does not provide wide range ‘burst’ mode dimming, rather dimming is provided by amplitude control of the output current waveform, this limits the potential dim range to typically less than 5:1. For applications not requiring wide range dimming, amplitude control results in lower ripple on the input supply and reduced potential transient noise generation. Many STN type panels are particularly well suited for current amplitude dimming. The modules convert a DC voltage from the system battery or AC adapter directly to high frequency, high-voltage waves required to ignite and operate CCFL lamps. A 12V input inverter is also available (LXM1618-12-6x). The inverter’s design is based on Microsemi’s new LX1689 backlight controller, which provides a number of cost and performance advantages due to the controller’s high level of integration. Other benefits of this new topology are stable fixed-frequency operation, secondary-side strike-voltage regulation and both open and shorted lamp protection with fault timeout.
