SERIES WHITE LED BACKLIGHT DRIVER 1MHz PWM STEP-UP DC-DC CONVERTER
DESCRIPTION
Features
The A8168 Series is a fixed frequency, constant current step-up DC/DC converter idea for driving LEDs used in backlighting application on cellular phones, PDAs and digital cameras etc. Output voltage of up to 17.5V can be derived, and from a 3.2V input four 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.
