1 / 16 page AT1312A/B/C Preliminary Product Information High Efficiency, Constant Current White-LEDs Driver 7F, No.9,PARK AVENUE. II, Science-Based Industrial Park, Hsinchu 300,Taiwan, R.O.C. Tel: 886-3-563-0878 Fax: 886-3-563-0879 WWW: http://www.aimtron.com.tw 2/23/2006 REV:1.1 Email: service@aimtron.com.tw 1 Feature •Operating Voltage:2.5V to 6.0V. •High Operating Frequency: 1MHz •High Output Voltage: Up to 16V/23V/28V •Shutdown Current <1 µA •16V/23V/28V Output Over-Voltage Protection •Digital Dimming Control. •Built-in Cycle-by Cycle Current-Limiting. •Built-in Soft-Start Function. •0.2V Low Reference Voltage •Tiny SOT-26 Package Application • LED Module • Compact Back Light Module • Constant Current Source Description The AT1312A/B/C 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 0.2V low reference voltage minimized the power loss across the current-setting resistor. The AT1312A/B/C is available in 6-pin SOT-26 packages. Block Diagram Aimtron reserves the right without notice to change this circuitry and specifications. |
