LX1695 - Switched Royer CCFL Inverter Monitor IC

General Description

KEY

Key Features

  • WWW . Microsemi . C OM The LX1695 is a general purpose DC to PWM generator with supervisory functions for switched Royer CCFL inverter modules used in single or multiple lamp desktop monitors and LCD TV sets. It integrates a PWM that generates digital (burst mode) dimming from a DC brightness control input, and a protection circuit that shuts off the Royer oscillator if lamp ignition does not occur in a timely manner, or in the event of one or more open lamps. Strike and initial open lamp time.
