AiT Semiconductor Inc. www.ait-ic.com A8169-025 LED BACKLIGHT DRIVER PWM MODE 23V STEP-UP SERIES WHITE LED DRIVER DESCRIPTION FEATURES The A8169-025 Series is a fixed frequency, constant  current step-up DC/DC converter ideal for driving LEDs  used in backlighting applications on cellular phones, PDAs and digital cameras etc. Output voltage of up to 23V  can be derived, and from a 3.2V input six white LED’s can  be driven in series or alternatively, using a 2.5V input, a  network of two parallel legs with three in each may be driven. Luminance of the LED’s is controlled by changing the duty  cycle of a PWM signal applied to the CE pin. In addition,  an internal MOSFET with an RDS(ON) of 0.8Ω is used.
