AS3689-T

Overview

The AS3689-T is a highly integrated CMOS power and lighting management unit manufactured by ams OSRAM. Designed primarily for mobile telephones and similar devices, it supplies power to LCD and camera modules using a single-cell battery configuration. The device functions as a DC-DC regulator with a step-up (boost) and switched capacitor (charge pump) topology. It provides fifteen outputs to manage various system requirements efficiently within compact electronic designs.

Feature Summary

• Highly integrated CMOS architecture combining power and lighting management
• Optimized for single-cell battery powered mobile applications
• Supports simultaneous power supply for LCD and camera modules

Applications

• Mobile telephone LCD power supply
• Camera module power management in smartphones
• Single-cell battery powered portable electronics

Procurement Notes

Verify the current availability status of the AS3689-T through authorized distributors or the manufacturer directly. Confirm that the specific suffix matches the required package and tape-and-reel specifications for your assembly line. Ensure compliance with relevant environmental regulations such as RoHS before finalizing procurement decisions for production runs.

Selection Notes

Select this component when designing systems requiring a unified solution for both display backlighting and camera flash power from a single cell. Consider its integration level if space constraints limit the use of discrete regulators. Evaluate whether the fifteen output channels meet the specific voltage and current demands of the target LCD and camera subsystems without external buffering.
