Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the VSON-14 package dimensions align with your PCB footprint requirements. Ensure compatibility with the required operating temperature range and verify RoHS compliance status through the latest product documentation before finalizing procurement.
Selection Notes
Select this component when a single-channel solution with an integrated switch is required for Boost or Buck-Boost LED configurations. It is suitable for designs needing flexible dimming control and wide input voltage ranges. Consider the VSON-14 package size for space-constrained layouts. Verify that the 2 A current capability meets the load requirements and that the thermal management strategy supports the specified operating temperature range.
Part Context
This part belongs to the TPS923653 series of non-synchronous Boost/Buck-Boost LED drivers. It is categorized under LED Lighting Drivers and Driver ICs by Texas Instruments. The device is designed for efficient power conversion in lighting applications, offering integrated protection features and flexible control options within a small form factor.
Replacement Considerations
Consult the official Texas Instruments selection guide for direct pin-to-pin or functionally equivalent alternatives within the same family. Verify that any substitute maintains the required VSON-14 package and electrical characteristics.
