Global Mixed-mode Technology Inc. AT1308A Micro-Power Step up DC-DC Converter Feature 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. Operating Voltage:2.5V to 6.0V. High Operating Frequency: 1MHz High Output Voltage: Up to 28V Shutdown Current <1μA Digital Dimming Control. Built-in Cycle-by Cycle Current-Limiting. Built-in Soft-Start Function. ±1.5% 1.23V Reference Voltage Tiny SOT-23-5 Package The AT1308A is available in 5-pin SOT-23-5 packages.
