DESCRIPTION
LEDs with a constant current to provide backlight in●High Operating Frequency: 1MHz cell phones, PDAs, and other hand-held devices. <1µA uniform brightness. An enable input can be pulsed
●16V/23V/28V Output Over-Voltage Protection repeatedly to adjust LED’s brightness. The fast 1.0
●Digital Dimming Control. MHz current-mode PWM control allows for smaller capacitor and inductor. Fault condition protection
●Built-in Cycle-by Cycle Current-Limiting. uses cycle-by-cycle current limiting to sense
●Built-in Soft-Start Function. maximum inductor current, thermal protection and
●0.2V Low Reference Voltage over-voltage protection. Also included soft-start eliminates inrush current during start-up. The 0.2V
●Tiny SOT-26 Package low reference voltage minimized the power loss across the current-setting resistor. Application
● LED Module
● Compact Back Light Module
● Constant Current Source 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.
