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 current CAN be set by an external resistor when LEDs are in-series connection, all white LEDs CAN be turned on equably. A network of two parallel legs with three in each LED CAN be also driven. Luminance of the LEDs is controlled by changing the duty cycle of a PWM signal applied to the CE pin. Efficiency is high with the low feedback reference voltage ensuring the RLED losses are minimal. In addition, an internal MOSFET with an RDSON of 2.0,, is used. A low profile and small board area solution CAN be achieved using a chip coil and an ultra small ceramic output capacitor (CL) of 0.22,F as a result of the high 1.0MHz switching frequency.
