It features high-efficiency DC-DC step-up converters with two current sources. The component utilizes a TQFP32 package and operates with Tape & Reel (TR) packaging. It is classified under LED Lighting Driver ICs.
Feature Summary
- Highly integrated, self-contained driver architecture optimized for compact form factors
- Designed specifically for near-to-eye display applications including AR and VR systems
- Incorporates high-efficiency DC-DC step-up conversion capabilities
Applications
- Augmented Reality (AR) glasses
- Virtual Reality (VR) headsets
- Near-to-eye display modules
Procurement Notes
Verify the part status carefully as this specific variant may be marked obsolete in certain distributor databases. Confirm the exact suffix ZTQT matches your design requirements, as base product numbers like AS3822 may have multiple packaging or performance variants. Ensure compatibility with your system's moisture sensitivity level (MSL 3) during assembly processes.
Selection Notes
Select this component when designing compact optical engines requiring integrated power management. The TQFP32 package offers a balance of thermal performance and footprint efficiency. Consider the two-current-source architecture if independent control of multiple LED arrays is required within the near-to-eye application constraints.
Part Context
This device belongs to the AS3822 family from ams OSRAM, focusing on LED driver solutions. It is distinct from other ams OSRAM products like laser diodes or photodiodes by its function as an active driver IC rather than a passive optical sensor or emitter. The technology supports the miniaturization trends in wearable optics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the part status is listed as obsolete in some channels, consult official ams OSRAM resources for current equivalent recommendations or next-generation replacements.
