... 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 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 ...

... Pin Function> The operation of the XC9133 series will enter into the shut down mode when a low level signal is input to the CE pin. During the shut down mode, the supply current is 0μA (TYP.), with high impedance at the Lx pin. The IC starts its operation with a high level signal to the CE pin. The input to the CE/MODE pin is a CMOS input and the sink current is 0 μ ...

... INFORMATION <Dimming Control> 1. Applying PWM signal to the CE pin The XC9133 repeats on/off operations by a PWM signal applied to the CE pin. The magnitude of LED current, I when the diode is on, is determined proportional to the positive duty ratio of the PWM signal. The frequency of the PWM signal can be controlled to the optimum value between 100Hz and 10kHz. With regard to the amplitude of the PWM signal, the high level should be higher than the " ...

... LEDs are open. Therefore, care must be taken if four LEDs each having a forward voltage of 4.45V or more are connected in series. <Startup Inrush Current> The XC9133 series has no soft-start circuit built-in in order to minimize delay at startup. The inrush current can reach up to the current limit I . ...

... Wire external components as close to the IC as possible and use thick, short connecting traces to reduce the circuit impedance. 4. Make sure that the PCB GND traces are as thick as possible, as variations in ground potential caused by high ground currents at the time of switching may result in instability of the IC. ●XC9133B Series Pattern Layout (SOT-25) XC9133 Series ) be connected as close as ...
