- Portable battery-powered LED devices
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the VSON-14 package dimensions align with your PCB footprint requirements. Check RoHS compliance status through the datasheet before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring a single-channel driver with integrated power switches. Ensure the application demands support for both step-up and step-down voltage conversion modes. Verify that the required operating frequency falls within the programmable range of 100 kHz to 2.2 MHz for optimal efficiency.
Part Context
This part belongs to the TPS923652 series of LED drivers designed for high-efficiency performance. It serves as a solution for applications needing compact size due to its surface-mount VSON-14 package. The device integrates protection features typically found in more complex discrete designs, simplifying system architecture.
Replacement Considerations
Consult the official TI product selection guide for direct functional equivalents within the same family. Verify pin-to-pin compatibility and electrical parameter alignment before substituting any alternative part numbers.
