XC9133 Datasheet (Torex) - Step-Up DC/DC Converter-LED Backlight Driver

XC9133, Step-Up DC/DC Converter-LED Backlight Driver

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 on
