Description
D R A FT D D R A FT D D R A FT D R D R A FT D D R A FT UBA2072 Rev.08.0 * February 2007 Low Voltage Full-bridge control IC for CCFL bac.
Features
* Wide supply voltage range (9 V to 30 V DC) Adjustable maximum fault timing Integrated level-shifters Integrated bootstrap diodes Lamp current control Over-voltage control Over-current protection Ignition failure detection Arcing detection Brightness level adjustment through PWM dimming Integrated PWApplications
* The IC contains level-shifters, bootstrap diodes and drivers for the external full-bridge power switches. Furthermore, the UBA2072 has a build-in HF oscillator which determines the operating frequency, a phase shift controller for obtaining constant lamp current, and a PWM generator which is used tHCPL-7721 Distributors
