6 / 6 page Microsemi Linfinity Microelectronics Division 11861 Western Avenue, Garden Grove, CA. 92841, 714-898-8121, Fax: 714-893-2570 Page 6 Copyright © 2000 Rev. 0.5,2001-01-18 RangeMAX ™ LXM1622-05-xx DUAL 5W, DIGITAL DIMMING CCFL INVERTER MODULE PRELIMINARY DATA SHEET A M I CROSEM I COM P A N Y '## '## (( )* )* (( + + The LMX1622-05-01 output current can be adjusted lower by changing the value of one resistor (R18) on the PCB. The following table shows the new output current values: Add R18 Output Current Resistor Value 6.5mArms Not used 6.0mArms 1.0M 5% 5.5mArms 422K 1% 5.0mArms 267K 1% 4.5mArms 178K 1% 4.0mArms 121K 1% 3.5mArms 88.7K 1% 3.0mArms 68.1K 1% The LMX1622-05-02,03 output current can be adjusted lower by changing the value of one resistor (R18) on the PCB. Changing the value of R35 can also increase the output current. The following table shows the new output current values: Add R18 Output Current Resistor Value 5.5mArms Not used 5.0mArms 845K 1%, 4.5mArms 374K 1%, 4.0mArms 232K 1% 3.5mArms 127K 1%, 3.0mArms 71.5K 1% Change R35 Output Current Resistor Value 5.5mArms 576 1% (stock value) 6.0mArms 499 1% 6.5mArms 442 1% The LMX1622-05-xx comes with a built in 5K pull-up resistor to allow the use of an external potentiometer for brightness adjust. In some cases this pull-up resistor may interfere with those driving the BRITE input from a high impedance. In this case the internal pull- up resistor R44 may be removed from the board. Please use the drawing below to help locate the specified resistor.
