This document is a technical specification sheet of RangeMAX LXM1622-05-xx DUAL 5W, DIGITAL DIMMING CCFL INVERTER MODULE product released by Microsemi Linfinity Microelectronics Division.
The Microsemi RangeMAX LXM1622-05-xx is a Direct Drive CCFL inverter module designed to drive two lamp LCD displays. It features a fixed 5V input voltage and utilizes a digital dimming technique to provide flicker-free brightness control with a range of 100:1 or greater. The module operates using a burst drive topology to ensure lamp longevity and includes protection features for open and shorted lamps.
| Input Supply Voltage | 4.75V to 5.25V |
|---|---|
| Output Power (-01) | 10.8 W |
| Output Power (-02,-03) | 6 W |
| Operating Frequency | 66 to 86 KHz |
| Fault Timeout | 1.6 SEC |
The module operates with an input supply voltage range of 4.75V to 5.25V.
It uses a fixed lamp current value with a duty cycle control method, modulating the burst width from 100% down to a 5% duty cycle.
The inverter will timeout and shutdown to protect the system.
