23V Reference Voltage •Tiny SOT-25 Package Description The AT1309 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.
4 MHz current-mode PWM control with a built-in 0.
3 Ω N-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 AT1309 is available in 5-pin SOT-25 packages.
Application • STN/OLED Bias • Personal Digital Assistants(PDAs) • DSC B...
