DIGITAL DIMMING QUAD LAMP CCFL INVERTER MODULE

T HE I NFINITE P OWER OF I NNOVATION

DESCRIPTION KEY FEATURES

RangeMAX Wide Range Dimming, Quad Output Inverter. The LXM1641 Direct

DriveTM CCFL (Cold Cathode Fluorescent Lamp) Inverter Modules are specifically designed for driving LCD backlight lamps.

Similar to the LXM1640, the LXM1641 excels in applications where critical parameters include very wide range dimmability, high efficiency and reliable fail-safe design in a small form factor. These 12 volt input modules are specifically designed with desktop and industrial applications in mind.

Unlike the LXM1640 or any traditional dimming CCFL inverters, the LXM1641 provides the designer a vastly superior display brightness range. 1000:1+ brightness range is achievable with a standard LCD display (see Application Section). Our wide range dimming provides exceptional display readability at less than 1% of full brightness, allowing both power savings and low ambient light operating capability (i.e. "night readable").

RangeMAX Digital Dimming Technique. Digital dimming provides flicker-free

brightness control in any wide-range dimming application. Dimming ratios greater than 1000:1 can be achieved. Incorporation of a video synchronization feature allows wide ratio dimming without the display disturbances and interference seen with competitive products.

The modules are equipped with a dimming input that permits brightness control from an external potentiometer or DC voltage source. The resultant "burst drive" that energizes the

lamp was designed specifically to ensure that no premature lamp degradation occurs (see "How RangeMAX Works" Section).

Failsafe Feature For Multiple Lamp Ap-

plications. Our multi-output inverters are

designed to keep your application operating at near normal brightness in the event that a lamp fails. This allows the display to remain "on-line" until lamp replacement is convenient.

Direct Drive Technology. The module

design is based on a new patented1 Direct Drive topology, which provides a number of cost and performance advantages. The LXM1641-xx Direct Drive inverters eliminate the classic resonant inductor and capacitors, thus reducing cost and allowing a substantial reduction in module size.

Universal Connector Configuration.

Linfinity's multiple lamp inverters include a built in connector array for the most common LCD lamp configurations.

Additional Features. Other benefits of

this new topology are fixed-frequency operation and secondary-side strike-voltage regulation.

Strike-voltage regulation minimizes corona discharge in the output transformer and related circuitry, providing longer life and higher reliability. All LXM1641 modules feature both open and shorted lamp protection.

The LXM1641 is fully customizable (electronically and mechanically) to specific customer requirements.

Connection Rules

1. Always install FOUR (4) lamps. Operating with fewer lamps may overdrive lamp current at maximum brightness settings.

2. Verify lamp wiring before connecting lamps to the inverter module. Connecting multiple lamps to one of the four inverter output

circuits will result in reduced brightness. The LXM1641-01 module connectors are wired per industry standard. The lamp hot wires (high voltage wires) are always on pin 1 or 2, and the cold wire (low voltage wire) is always on pin 3 or 4.

Linfinity inverters have multiple lamp connector styles that are common to the industry, which are duplicated at both ends of the module.

Rather than using the traditional dimming technique of varying lamp current magnitude to adjust light output, RangeMAX inverters use a fixed lamp current value with a duty cycle control method.

The lamp current burst width can be modulated from 100% (continuous lamp current) down to a 2% duty cycle, allowing the lamp to be dimmed to less than 1% of its full brightness.

As can be seen in Trace 4 of Figure 8, careful design consideration was given to controlling lamp start voltage to softly start current flow. This eliminates current overshoot that can result in premature cathode wear and reduce lamp life.

HOW RANGEMAX WORKS (continued)

HIGHLIGHTS

■ On-board brightness control circuit includes a DC voltage

to pulse width converter that minimizes system design work and system noise susceptibility. This provides a familiar and convenient interface while reducing the potential for externally induced noise which can cause lamp flicker.

■ An on-board oscillator operates the inverter BURST rate

above 95Hz, well beyond standard 50/60Hz video refresh rates where the eye can perceive pulsing light.

■ RangeMAX inverter modules are designed to operate with

the burst frequency synchronized to the video frame rate. This provides operation with no visible display disturbances caused by beat frequencies between the lamps and video frame rates.

TYPICAL 100:1 DIMMING APPLICATION

RangeMAX

■ In applications with no access to a vertical sync, the in-

verter burst frequency can be allowed to "free run" at 95Hz. In this non-synchronous mode, minor display disturbances may be found under certain video conditions. This performance is acceptable for many applications, but synchronization must be used when no disturbance can be tolerated.

■ Separate feedback loops for lamp current and open circuit volt-

age regulation insure reliable strike under all operating conditions, automatic over-voltage prevention with broken or failed lamps, and accurate lamp current regulation.

1000:1 DIMMING APPLICATION

The following application defines techniques capable of delivering dimming ranges in the 250:1 and 1000:1 range. As is widely understood, these techniques will provide general capabilities and actual system performance will vary with panel design, CCFTs, ambient temperature and a number of other variables outside the control of the inverter. These methods can be used in conjunction with other techniques such as lamp heating and matching.

Wide ratio (1000:1) dimming can be accomplished using the Linfinity

inverter in two ways:

1) By varying the input voltage on the brightness pin as indicated in Figure 12. Caution must be exercised when applying negative voltage to the brightness control input. Applying more than -300mV to any inverter input will cause inverter malfunction (see Absolute Maximum Ratings).

2) By making a resistor value change on the module. If this option is preferrable, please contact the factory for application assistance.

Both methods discussed will provide a lower duty cycle

operation than is necessary in a 100:1 dimming application.

Careful consideration should be made with regards to display quality

FAILSAFE FEATURE FOR MULTIPLE LAMP OPERATIONS

Our multi-output inverters are designed to keep your application operating at near normal brightness in the event that a lamp fails. This allows the display to remain "on-line" until lamp replacement is convenient.

Linfinity "parallels" the lamps so that if any lamps break, most of the current is added to the remaining good lamps. CCFLs will respond with more brightness for a period of time. Operating time in this mode will be a function of the lamps age but should be typically in the order of hundreds of hours.

This operating characteristic can provide adequate display performance for a limited, but useful period of time. Shortening of the lamp life in this mode is typically not a concern as it is recommended that all lamps in a display be replaced at the same time.
