UBA2072 Product details

Description

D D R A FT D R The UBA2072 is a low voltage IC intended to drive Cold Cathode Fluorescent Lamps (CCFLs) for back-lighting applications.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 to set the brightness level of the CCFLs.The UBA2072 is design

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 PWM generator 3.
