Procurement Notes
Verify the specific ordering suffix 'YZGR' against the manufacturer's official documentation to ensure correct package type and tape/reel specifications. Confirm that the required input voltage range and output current ratings align with the target LED string configuration before procurement.
Selection Notes
Select this component when a compact solution for driving high-power LEDs is required. The 2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the thermal design accommodates the power dissipation inherent in the DSBGA package under maximum load conditions.
Part Context
This part belongs to the TPS6105x series of LED drivers from Texas Instruments. It shares architectural similarities with the TPS61060 and TPS61062 but differs in output current capacity and specific feature sets. It is distinct from the TPS61062YZFR, which offers different electrical characteristics and pin configurations.
Replacement Considerations
The TPS61062YZFR is a related component within the same product family. Verify compatibility regarding pinout, control interface, and electrical parameters before substitution, as differences in output current and internal architecture may exist.
