DESCRIPTION

Microsemi’s LX1691 is a cost reduced, enhanced feature set, Direct Drive CCFL (Cold Cathode Fluorescent Lamp) Controller. Its architecture is based on the very popular LX1689. By limiting VDDP to 5.5V and using advanced processing, die size and package pin count is decreased while improving dimming precision.

LX1691 based inverter modules can be designed for virtually any CCFL appliance from digital cameras and PDA’s to big screen monitors and driver viewable automotive displays.
