Description
The AT1308 step-up converter is designed for
*all or medium size LCD panel of high bias
voltage with a constant current to provide PDAs,
and other hand-held devices. It features a fast 1.0
MHz current-mode PWM control with a built-in
0.3Ω N-MOS that allows for *aller capacitor and
inductor. Fault condition protection uses cycle-bycycle
current limiting to sense maximum inductor
current and thermal protection. Also included
soft-start circuitry eliminates inrush current during
start-up. The AT1308 is available in 5-pin SOT-25
packages.

Application
• STN/OLED Bias
