Quick Detail:
Digital Dimming CCFL Controller IC
Description:
The LX1686E Backlight Controller IC provides all the control functions
needed to implement Microsemi’s direct drive inverters used to operate
cold cathode fluorescent lamps (CCFL’s). This IC can be used to control single or multiple-lamp configurations. CCFL’s are used for back or edge lighting of liquid crystal flat panel displays (LCD’s) and typically find application in notebook computers, web browsers, automotive
and industrial instrumentation, and entertainment systems.
The LX1686E includes a PWM controlled lamp current burst circuit
that can provide a > 100:1 dimming range from a simple zero to 2.5V
potentiometer input. The PWM dimming burst rate is easily
synchronized to the LCD panel’s frame rate to prevent interference from optical beat frequencies.
Safety and reliability features include a new dual feedback control loop that permits regulation of maximum lamp strike voltage as well as lamp current.
Regulating maximum lamp voltage permits the designer to provide for
ample worst case lamp strike voltage while at the same time conservatively limit maximum open circuit voltage.
An innovative new strike voltage generation technique enables the
module designer to optimize high voltage transformer design for
maximum operating efficiency with no power dissipating overhead to guarantee strike capability Direct drive topology is a nonresonant, oscillator-controlled PWM regulation method. The LX1686E allows a wide choice of fixed operating frequencies to match lamp current
frequency to the lamp’s most efficient operating point, and to minimize high frequency interference.
Applications:
-- RangeMAX™ Wide Range Dimming (>100:1)
-- Synchronizable to Display Video Frequency
-- High Voltage Feedback Loop Directly Controls Maximum Open Lamp
-- Micro-Amp Sleep Mode
-- User Programmable Fixed Frequency Operation
-- Under-Voltage Lockout Feature With Power-Up Reset
-- Built-In Soft-Start Feature
-- Operates With 3.3V or 5V power Supplies 100mA Output Drive Capability
