Datasheet	AT1316A Datasheet

The AT1316A step-up converter drives white LEDs with a constant current to provide backlight in cell phones, PDAs, and other hand-held devices.

Global Mixed-mode Technology High Efficiency, Constant LEDs Driver Current AT1316A 20V White- Feature Operating Voltage: 2.5V to 5.5V.

High Operating Frequency: 1MHz High Output Voltage: Up to 20V(Typ.) Digital Dimming Control.

Built-in Cycle-by Cycle Current-Limiting.

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 1.0 MHz current-mode PWM control allows for smaller capacitor and inductor. Fault condition protection uses cycle-by-cycle current limi.
