General Description

The ACE714B 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 28V can be derived, and from a 2.5V input three white LED’s can be driven in series.

Luminance of the LED’s is controlled by changing the duty cycle of a PWM signal applied to the CE pin.
