Additional Infomation About Product

UBA3070 LED backlight driver IC Rev. 3 9 December 2010 Product data sheet 1. General description The UBA3070 driver IC is the first member of a first generation of power-efficient LED backlight driver ICs. Highly efficient, flexible and reliable LED drivers can easily be designed using the UBA3070 control IC. 2. Features and benefits Switch-mode buck controller that drives strings of LEDs up to 600 V power-efficiently Controller with power-efficient Boundary Conduction Mode (BCM) operation: Virtually no reverse recovery losses in freewheel diode Zero Current Switching (ZCS) at switch, switch-on Zero voltage or valley switching at switch, switch-on Minimal required inductance value and size Suitable for direct Pulse Width Modulation (PWM) dimming Fast transient response through cycle-by-cycle current control, thereby: Preventing over or undershoots in the Light Emitting Diode (LED) current Enabling efficient PWM dimming by quickly turning the converter on and off and thus removing the need for extra dimming switches and high-side drivers Single controlled input voltage required for all UBA3070 driven LED strings in RGB or white backlighting units No binning on LED forward voltage required Protections: UnderVoltage LockOut (UVLO) Leading Edge Blanking (LEB) OverCurrent Protection (OCP) OverTemperature Protection (OTP) Low cost LED driver solution: No fast-switching Schottky diode required due to ZCS No dimming switch or high-side driver required for PWM dimming Operates with smaller inductor then a comparable fixed-frequency Continuous Conduction Mode (CCM) controller 3. Applications The UBA3070 is suitable for high voltage LED lighting application: LED backlighting in LCD televisions and monitors General lighting applications The UBA3070 application is most efficient when driving long LED stringsUBA3070 NXP Semiconductors LED backlight driver IC 4.
