UBA2071 Product details

Description

The UBA2071 and UBA2071A are high voltage ICs intended to drive Cold Cathode Fluorescent Lamps (CCFLs) or External Electrode Fluorescent Lamps (EEFLs) for backlighting applications.

Features

I I I I I I I I I I I I I Suitable for operating in a very wide inverter supply voltage range (up to 550 V DC). Integrated level shifter. Integrated bootstrap diode. Lamp current control by means of a true zero voltage switching resonant control principle. Sample & Hold circuit, maintaining current control value during PWM lamp-off situation. Separately deﬁnable time constants for current control loop and PWM dimming attack/decay setting. Overvoltage control. Overcurrent protection. Ignition fai.
