Overview
The AAT3190IKS-T1 is a dual-output DC-DC controller and switched-capacitor charge pump designed for LED lighting applications. Manufactured by Skyworks Solutions, Inc., this component operates within an input voltage range of 2.7 V to 5.5 V and supports a switching frequency of 1 MHz. It is housed in an 8-pin MSOP package and provides two independent outputs for driving LED strings. The device integrates dimming control capabilities and is classified under LED drivers and PMIC categories.
Feature Summary
- Dual-output architecture enabling independent control of multiple LED strings
- Integrated switched-capacitor charge pump topology for efficient voltage conversion
- Supports dimming control functions for adjustable brightness management
Applications
- Portable LED lighting systems
- Battery-powered illumination devices
- General LED driver circuits requiring dual outputs
Procurement Notes
Verify component status as the AAT3190IKS-T1 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing PCB footprints and design requirements before sourcing. Check for moisture sensitivity level and handling precautions during procurement and storage.
Selection Notes
Select this component for designs requiring dual-channel LED drive from a single IC. Consider the 1 MHz switching frequency for compact passive component sizing. Evaluate the 8-MSOP package constraints for thermal and spatial limitations. Verify input voltage compatibility with the system power source.
Part Context
This part belongs to Skyworks' AAT series of analog and mixed-signal integrated circuits. It falls under the broader category of Power Management ICs (PMIC) and specifically LED lighting drivers. The series typically targets portable electronics and battery-operated devices requiring efficient power regulation and LED control.
Replacement Considerations
As the part is obsolete, identify equivalent dual-output charge pump LED drivers from current Skyworks portfolios or other manufacturers. Verify pinout compatibility and electrical specifications such as input voltage range and output current capabilities when selecting substitutes.
