Step-Up DC/DC Converter-LED Backlight Driver

■GENERAL DESCRIPTION

The XC9133 series is a fixed frequency, constant current step-up DC/DC converter which is optimized for LED backlight

applications in mobile phones, PDAs and digital cameras. Output voltage of up to 17.5V is possible so that four white LEDs

can be driven in series. Since the LED current is set by only one external resistor, all white LEDs placed in series can be

turned on at the same time. The new DC/DC Converter is also able to drive a network of two parallel banks of three LEDs.

LED dimming is controlled by adjusting the duty cycle of a PWM signal (10kHz Max.) applied to the CE pin.

Efficiency is high with a 0.2V low feedback reference voltage ensuring the RLED losses are minimal. In addition, an internal

MOSFET with a low RDSON of 2.4Ω is used. A low profile and small board area solution can be achieved using a chip

inductor and a small ceramic output capacitor CL=0.22μF as a result of the high 1MHz switching frequency.

If white LEDs are opened or damaged, the detector built in the Lx pin causes the IC to stop oscillating, preventing excessive

increase of the output voltage.
