Description:

High Efficiency Constant Current White-LED Driver

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-

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
