Description
The AT1308A step-up converter is designed for small
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 0.3ΩN-MOS that allows for
smaller capacitor and inductor. Fault condition
protection uses cycle-by-cycle current limiting to sense
maximum inductor current and thermal protection. Also
included soft-start eliminates inrush current during
start-up.
The AT1308A is available in 5-pin SOT-23-5 packages.
