CURRENT MANUFACTURER OFFERS - UBA3070 LED backlight driver IC

The UBA3070 driver IC is the first member of a first generation of power-efficient LEDbacklight driver ICs. Highly efficient, flexible and reliable LED drivers can easily be designed using theUBA3070 control IC. Features • Switch-mode buck controller that drives strings of LEDs up to 600V power-efficiently • Controller with power-efficient boundary conduction mode of operation:  No reverse recovery losses in freewheel diode   Zero current switching for turn-on of switch   Zero voltage or valley switching for turn-on of switch   Minimal required inductance value and size • Direct Pulse Width Modulation (PWM) dimming available • Fast transient response through cycle-by-cycle current control, thereby:   Preventing over or undershoots in the LED current   Enabling efficient PWM dimming by quickly turning the converter on and off and thereby removing the need for extra dim switches and high-side drivers • Single loosely controlled input voltage required for all LED strings in RGB backlights • No binning on LED forward voltage required • Protections:   Under-voltage lock-out   Leading edge blanking   Over-current   Over-temperature • Low cost LED driver solution:   No Schottky diode required because of zero-current switching   No dim switch and high-side driver required for PWM dimming   Smaller inductor possible compared to fixed-frequency continuous conduction mode controllers Want to apply for this board?
