XC9116 Datasheet (Torex Semiconductor) - Step-Up DC/DC Converter-Backlight LED Driver

XC9116, Step-Up DC/DC Converter-Backlight LED Driver

The XC9116 series is a fixed frequency, constant current step-up DC/DC converter ideal for driving LEDs used in backlighting applications such as cellular phones, PDAs and digital cameras.

Output voltage of up to 17.5V can be derived, therefore four white LEDs in series can be driven.

Since an LED c
