UBA2071A - Half bridge controller
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.
They can drive a half bridge circuit made up of two NMOSFETs with a supply voltage of up to 550 V, so the inverter can
UBA2071A 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
