AT1313 High Efficiency Constant Current White-LED Driver

AT1313 Description

www.DataSheet4U.com AT1313 High Efficiency, Constant Current White-LED Driver .
The AT1313 step-up converter drives white LEDs with a constant current to provide backlight in cell phones, PDAs, and other hand-held devices.

AT1313 Features

* allowing series connection of the white LEDs so that the LED currents are identical for uniform brightness. An enable input can be pulsed repeatedly to adjust LED’s brightness. The fast 1.4 MHz current-mode PWM control allows for smaller capacitor and inductor. Fault condition protection uses cycle-

AT1313 Applications

* The output voltage of the step-up converter can be set from Vin to 16V with external sense resistor. The device suits to drive series-connected LEDs and provides even illumination by sourcing the same output current through each LED. AT1313 also consists of a logic shutdown , cycle-by-cycle current
