Description
The AT1316A step-up converter drives white LEDs with a
constant current to provide backlight in cell phones, PDAs,
and other hand-held devices. It 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 1.0
MHz current-mode PWM control allows for smaller
capacitor and inductor. Fault condition protection uses
cycle-by-cycle current limiting to sense maximum inductor
current, thermal protection and over-voltage protection.
Also included soft-start eliminates inrush current during
start-up. The low reference voltage minimized the power
loss across the current-setting resistor.
The AT1316A is available in TSOT-23-6 packages.
